### 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 --…

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…
