Title: Mapping Space Signatures</span></font></div><div><font style="font-family:Calibri,Helvetica,sans-serif,serif,&quot;EmojiFont&quot;" size="3" face="Calibri,Helvetica,sans-serif" color="black"><span style="font-size:12pt">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.</span></font></div></div>
