A fully faithful p-adic Riemann--Hilbert functor for filtered coherent D-modules

Finn Wiersig

We prove that the solution functor from bounded good filtered complexes of coherent D-modules on a smooth rigid-analytic variety to modules over the positive almost de Rham period…

The p-adic Cauchy Theorem and Overconvergent Period Sheaves

Finn Wiersig

The classical p-adic Cauchy theorem asserts that formal solutions of ordinary p-adic differential equations are convergent. In this article we establish a geometric analogue of thi…

A fully faithful p-adic Riemann-Hilbert functor for coadmissible D-cap-modules

Finn Wiersig

This article establishes a Riemann-Hilbert correspondence in rigid-analytic geometry. We construct an explicit solution functor and prove that it is fully faithful on Ardakov-Wadsl…

Galois and Pro-étale Cohomology of Overconvergent de Rham Period Rings

Finn Wiersig

Motivated by the theory of p-adic differential equations and p-adic geometric representation theory, we introduce overconvergent variants of Fontaine's classical period rings. In p…

No short polynomials vanish on bounded rank matrices

Jan Draisma, Thomas Kahle, Finn Wiersig

We show that the shortest nonzero polynomials vanishing on bounded-rank matrices and skew-symmetric matrices are the determinants and Pfaffians characterising the rank. Algebraical…

Short polynomials in determinantal ideals

Thomas Kahle, Finn Wiersig

We show that a determinantal ideal generated by -minors does not contain any nonzero polynomials with or fewer terms. Geometrically this means that any nonzero polynomial…
