### Melvyn Nathanson – City University of New York

Solved and unsolved problems in additive number theory This will be a survey of recent results in combinatorial and additive number theory. The central object is the set of sums of elements in a finite or infinite set of integers. This…

### Gengran Hu – Hangzhou Dianzi University

On reductions from subset sum problem to shortest vector problem. The shortest vector problem (SVP) is a fundamental problem in lattice theory and its applications in cryptography. The hardness of SVP is established by constructing reductions from the subset sum problem to SVP.…

Multivariate cryptography and Groebner bases -- Colloquium talk Multivariate cryptography is one of a handful of proposals for post-quantum cryptographic schemes, i.e., cryptographic schemes that are secure also against attacks carried on with a quantum computer. Their security relies on…

Rank-metric codes and q-polymatroids Rank-metric codes are vector subspaces of the vector space of matrices of given size over a finite field, equipped with the distance function induced by the rank. After an introduction to rank-metric codes, I will introduce q-polymatroids --…

Universal Groebner bases and Cartwright-Sturmfels ideals Universal Groebner bases are systems of generators of ideals, which are a Groebner basis with respect to any term order. In this talk, I will introduce a family of ideals named after Cartwright and…

Jensen-Pólya Criterion for the Riemann Hypothesis and Related Problems In this talk, I will summarize forthcoming work with Griffin, Ono, and Zagier. In 1927 Pólya proved that the Riemann Hypothesis is equivalent to the hyperbolicity of Jensen polynomials for Riemann's Xi-function. This hyperbolicity has…

### Daniel Apon – National Institute of Standards and Technology

NIST's Post-Quantum Cryptography Project (2012-2024) In recent years, there has been a substantial amount of research on quantum computers – machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional (classical/digital) computers. If…

Sum-Rank Codes and Linearized Reed-Solomon Codes The sum-rank metric naturally extends both the Hamming and rank metrics in coding theory. In this talk, we will present linearized Reed-Solomon codes, which constitute the first general family of maximum sum-rank distance (MSRD)…
