Talk: An algebraic geometry of paths via the iterated-integral signature
Published: July 1, 2024 10:00
I gave this talk on March 20, 2024 at the Nonlinear Algebra Seminar at MPI MiS Leipzig. Abstract: _Contrary to previous approaches bringing together algebraic geometry and signatures of paths, we introduce a Zariski topology on the space of paths itself,…

I gave this talk on March 31, 2022 (which also happens to be Trans Day of Visibility) at Technische Universität Berlin for the Rough Algebra Day organised by Yannic Vargas, Sylvie Paycha, Bernd Sturmfels and Peter Friz. Abstract: In this presentation we…
Online talk: In how far is the path characterized by the signature?
Published: February 21, 2022 05:26
I gave this talk on February 04, 2022 in the analysis seminar of Sylvie Paycha of University of Potsdam, which happened online on zoom. Abstract: The aim of our project is to give a definite answer to the question posed (in its earliest form) by Chen some…
