Numerical Solution of Free Stochastic Differential Equations
Georg Schluechtermann, Michael Wibmer
This paper derives a free analog of the Euler-Maruyama method (fEMM) to numerically approximate solutions of free stochastic differential equations (fSDEs). Simply speaking fSDEs a…
Regular singular differential equations and free proalgebraic groups
Michael Wibmer
We determine the differential Galois group of the family of all regular singular differential equations on the Riemann sphere. It is the free proalgebraic group on a set of cardina…
Differential Galois groups, specializations and Matzat's conjecture
Ruyong Feng, Michael Wibmer
We study families of linear differential equations parametrized by an algebraic variety and show that the set of all points , such that the differen…
A remark on torsors for affine group schemes
Michael Wibmer
We present an elementary proof of the fact that every torsor for an affine group scheme over an algebraically closed field is trivial. This is related to the uniqueness of fibre fu…
