Arbeitsgruppenseminar Analysis

Rosa Preiss (TU Berlin)

Varieties of signature tensors were introduced by Améndola-Friz-Sturmfels in 2019. In this informal talk, I will give an overview of the works that followed this groundbreaking article, introduce the halfshuffle map M_p adjoint to a polynomial map p and hint current WIP.

Based on joint work with Annika Burmester, Steven Charlton, Laura Colmenarejo, Abhiram Kidambi, Felix Lotter. Special thanks to Francesco Galuppi.
