This combined lecture series brings together two significant advances in differential and Riemannian geometry, focusing on the interplay between algebraic structures and global geometric phenomena. **Integrability of Lie Algebroids — Rui Loja Fernandes** In a comprehensive 1 hour 32 minute lecture, Rui Loja Fernandes reviews the foundational and recent developments in the **integrability of Lie algebroids**. Lie algebroids, which generalize Lie algebras and tangent bundles, serve as a crucial framework connecting differential geometry with algebraic structures. Fernandes systematically covers: - The main criteria and obstructions for integrability, including the role of monodromy groups and differentiation of Lie groupoids. - Geometric and topological conditions under which a Lie algebroid can be integrated to a Lie groupoid. - Applications highlighting how these integrability conditions impact the study of foliations, Poisson structures, and geometric quantization. This lecture deepens understanding of how algebraic and analytic methods converge in the study of smooth manifolds, providing tools that bridge local infinitesimal data with global topological properties. **Lengths of Closed Geodesics in Manifolds of Positive Scalar Curvature — Yevgeny Liokumovich** In a complementary 58 minute talk, Yevgeny Liokumovich investigates the **lengths of closed geodesics in Riemannian manifolds with positive scalar curvature**. His analysis addresses fundamental questions about how curvature constraints influence the global geometry of closed geodesics: - Techniques to estimate minimal and maximal lengths of closed geodesics on manifolds exhibiting positive scalar curvature. - Interactions between scalar curvature bounds and the existence, multiplicity, and length spectrum of closed geodesics. - Implications for rigidity phenomena and geometric inequalities, linking scalar curvature conditions to global topological and dynamical properties. Liokumovich’s talk contributes to understanding how curvature conditions impose constraints on geodesic behavior, a central theme in global Riemannian geometry. --- **Significance and Interconnections** Together, these lectures highlight a profound relationship linking algebraic integrability conditions of Lie algebroids with global geometric features such as closed geodesics under curvature constraints: - The integrability of Lie algebroids provides a conceptual and technical framework that can influence the study of foliations and geodesic flows on manifolds. - Scalar curvature conditions, by controlling geodesic lengths, relate to topological invariants and can be studied via techniques that are informed by integrability properties of underlying algebraic structures. - These results illustrate the deep synergy between algebraic and analytic methods in geometry, opening pathways for future research bridging differential geometry, topology, and global analysis. This pairing of talks advances the frontier of geometric understanding by connecting algebraic integrability with global metric properties, enriching both the theory and applications within modern geometry.

The landscape of **post-quantum cryptography** continues to evolve rapidly, driven by the urgent need to secure digital communications against the looming threat of quantum computers. Among the forefront of this evolution is the innovative fusion of **graph-theoretic spectral invariants**, **immanantal polynomials**, and **convex geometric structures**—notably **symmetric edge polytopes**—to forge new foundations for quantum-resistant digital signatures. Recent advances have significantly deepened the mathematical underpinnings of these approaches, integrating profound results from algebraic combinatorics, spectral graph theory, and convex geometry to strengthen both theoretical rigor and practical viability. --- ### Expanding the Cryptographic Frontier: New Mathematical Tools and Insights Building on prior recognition of the spectral complexity of graph Laplacians as a hardness resource, researchers have now incorporated powerful convex-geometric inequalities and refined combinatorial structures, broadening the arsenal of cryptographic hardness assumptions. #### Mixed Ehrhart Theory and Alexandrov–Fenchel-Type Inequalities: A Geometric Breakthrough One of the most notable recent developments is the application of **mixed Ehrhart theory** and **Alexandrov–Fenchel-type inequalities** to symmetric edge polytopes. These polytopes, constructed from the edges of graphs as centrally symmetric convex bodies, have long been recognized for their rich combinatorial and algebraic properties. The introduction of mixed Ehrhart theory—a framework analyzing how lattice points scale within polytopes—and Alexandrov–Fenchel inequalities—a cornerstone of convex geometry relating mixed volumes—has provided new quantitative tools to estimate and bound polytope invariants tightly connected to spectral graph properties. **Joel Hakavuori’s recent work** illustrates this synergy, revealing that these inequalities yield robust constraints on the combinatorial volumes and face structures of symmetric edge polytopes. This not only enhances our understanding of their geometric complexity but, crucially, reinforces the **geometric hardness assumptions** used in cryptographic constructions grounded on these polytopes. The impact is a stronger, more nuanced security foundation that complements spectral and algebraic hardness. #### Combinatorial Expressions for the Second Immanantal Polynomial Parallel to these geometric advances, breakthroughs in algebraic combinatorics have yielded **explicit combinatorial formulae for the second immanantal polynomial of the signless Laplacian matrix**. This polynomial generalizes the characteristic polynomial and encodes sophisticated graph invariants that go beyond eigenvalues alone. The new expressions allow for concrete computational interpretations and provide fresh hardness assumptions based on the complexity of evaluating or inverting these polynomials. Such algebraic complexity is particularly promising for cryptographic applications, as it has resisted both classical and quantum algorithmic attacks to date. The ability to link these polynomials directly to graph structures used in signature schemes means that cryptographers can design primitives with finely tunable hardness parameters. #### Structural Advances on Extremal Eigenvalues and Graph Minors Further strengthening the framework are recent results on the behavior of **extremal eigenvalues under graph minor operations**—such as edge deletions and contractions—that highlight how spectral invariants transform under natural graph modifications. Understanding these transformations is critical since adversaries might attempt to simplify or alter graph structures to undermine spectral hardness assumptions. The new characterizations provide: - **Tight bounds on eigenvalue variations** when taking minors, ensuring that essential spectral properties remain stable or vary predictably. - **Insights into the robustness of spectral hardness assumptions**, confirming that minor operations cannot trivially weaken the cryptographic security. - A pathway to **designing signature schemes resilient to structural graph attacks**, by selecting graph families whose spectral invariants exhibit extremal stability. --- ### Significance: Toward a Diversified and Robust Post-Quantum Cryptographic Ecosystem These cutting-edge mathematical developments collectively enrich the post-quantum cryptography landscape by: - **Strengthening security assumptions**: The interplay of spectral graph theory, algebraic combinatorics, and convex geometry produces multilayered hardness foundations not currently threatened by known quantum algorithms. - **Broadening the mathematical toolkit**: Moving beyond classical number-theoretic or lattice-based assumptions, graph-based constructions augmented with geometric inequalities and immanantal polynomials diversify potential signature schemes, mitigating the risk of systemic vulnerabilities. - **Informing standardization and implementation**: As NIST and other bodies evaluate post-quantum candidates, these new frameworks offer promising directions for future protocols that balance security with efficiency and scalability. - **Enabling cross-disciplinary innovation**: The convergence of distinct mathematical domains fosters collaboration across spectral theory, combinatorics, geometry, and quantum complexity, accelerating both theoretical insights and cryptanalytic evaluations. --- ### Challenges and Forward Outlook While the progress is promising, several challenges remain: - **Cryptanalysis and Quantum Resistance Validation**: Rigorous efforts are essential to confirm that the newly introduced geometric and algebraic hardness assumptions withstand evolving quantum algorithms, including potential breakthroughs in quantum spectral analysis or lattice reduction analogues. - **Optimizing Practical Performance**: To transition from theory to practice, signature schemes based on these constructions must achieve competitive key sizes, signature lengths, and computational overheads. - **Exploration of Further Mathematical Structures**: The success of mixed Ehrhart theory and Alexandrov–Fenchel inequalities invites exploration of other convex-geometric and topological invariants that could yield new cryptographic primitives. - **Sustained Interdisciplinary Collaboration**: Realizing the full potential of these approaches requires ongoing dialogue among mathematicians, cryptographers, and quantum computing experts. --- ### Conclusion The integration of **mixed Ehrhart theory**, **Alexandrov–Fenchel-type inequalities**, and refined **immanantal polynomial** characterizations into the study of **spectral graph invariants** and **symmetric edge polytopes** marks a significant milestone in the quest for quantum-resistant digital signatures. These advances not only deepen the theoretical foundations but also pave the way for innovative, robust, and scalable cryptographic schemes resilient against the quantum horizon. As this vibrant research area matures, the synergy between spectral graph theory, algebraic combinatorics, and convex geometry promises to unlock new cryptographic paradigms—ensuring that the security of our digital infrastructure remains steadfast amid the transformative challenges posed by quantum computing.
