Bismut type differentiation of semigroups
by Marc Arnaudon and Anton Thalmaier
We present a unified approach to Bismut type differentiation formulas
for heat semigroups on functions and forms.
Both elliptic and hypoelliptic situations are considered.
Nonlinear extensions apply to the case of harmonic maps
between Riemannian manifolds and solutions to the nonlinear heat equation.
