Dear Colleagues, we would like to invite you to the following seminar by Darrick Lee (EPFL) to be held tomorrow (May 10th) at Dipartimento di Matematica in Pisa and online via Google Meets.
The organizers, A. Agazzi and F. Grotto
Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg
Time: May 10th, 2022, 14:00-15:00 CET Speaker: Darrick Lee (EPFL) Title: Mapping Space Signatures Abstract: The path signature is a foundational tool in the theory of rough paths. In this talk, we introduce the mapping space signature, a generalization of the path signature to maps from higher dimensional cubical domains, which is motivated by the topological perspective of K. T. Chen. We show that the mapping space signature shares many of the analytic and algebraic properties of the path signature; in particular it is universal and characteristic with respect to a certain equivalence relation on cubical maps. This is joint work with Chad Giusti, Vidit Nanda, and Harald Oberhauser.
