HEAT EQUATIONS AND THE WEIGHTED ¯ ∂-PROBLEM

By  and Andrew Raich and Andrew Raich

Abstract

Abstract. The purpose of this article is to establish regularity and pointwise upper bounds for the (relative) fundamental solution of the heat equation associated to the weighted ¯ ∂-operator in L 2 (C n) for a certain class of weights. The weights depend on a parameter, and we find pointwise bounds for heat kernel, as well as its derivatives in time, space, and the parameter. We also prove cancellation conditions for the heat semigroup. We reduce the n-dimensional case to the one-dimensional case, and the estimates in one-dimensional case are achieved by Duhamel’s principle and commutator properties of the operators. As an application, we recover estimates of heat kernels on polynomial models in C 2. 1
