Borel summation of the small time expansion of the heat kernel with a vector ...
We study the Borel summability of the small time expansion of the heat kernel associated to a first order perturbation of a Laplacian. An explicit formula for this... -
A deformation formula for the heat kernel
Let us consider a time-dependent differential operator quadratic with respect to the phase variables. Let us consider a multiplication operator defined with the help...
