Global Homotopies for Differential Hochschild Cohomologies
Marvin Dippell, Chiara Esposito, Jonas Schnitzer +1
We construct explicit global homotopies for differential Hochschild cochains in differential geometry, thereby upgrading the classical Hochschild-Kostant-Rosenberg map to a deforma…

Convergent Twist Deformations
Chiara Esposito, Michael Heins, Stefan Waldmann
This paper establishes a functorial framework for convergence of Drinfeld's Universal Deformation Formula (UDF) on spaces of analytic vectors. This is accomplished by matching the…
