Heat Content Asymptotics with Singular Initial Temperature Distributions
We study the heat content asymptotics with either Dirichlet or Robin boundary conditions where the initial temperature exhibits radial blowup near the boundary. We show that there is a complete small-time asymptotic expansion and give explicit geometrical formulas for the first few terms in the expansion.
متن کاملHeat content asymptotics for Riemannian manifolds with Zaremba boundary conditions
The existence of a full asymptotic expansion for the heat content asymptotics of an operator of Laplace type with classical Zaremba boundary conditions on a smooth manifold is established. The first three coefficients in this asymptotic expansion are determined in terms of geometric invariants; partial information is obtained about the fourth coefficient.

We study the heat content asymptotics on a Riemannian manifold with smoooth boundary defined by Dirichlet, Neumann, transmittal and transmission boundary conditions. Subject Classification: 58J50
متن کاملThe Heat Content Asymptotics of a Time Dependent Process
Let M be a compact manifold with smooth boundary. We study the heat content asymptotics on M defined by a time dependent heat source and time dependent boundary conditions. We adopt the following notational conventions: let M be a compact Riemannian manifold with smooth boundary ∂M , let ∆ = δd be the scalar Laplacian on M , let x be a point of the interior of M , let y be a point of the bounda...
