It is well-known that the embedding of the Sobolev space of weakly differentiable functions into Hölder spaces holds if the integrability exponent is higher than the space dimension. In this paper, the embedding of the Sobolev functions into the Hö

We prove the necessary and sufficient condition for the removability of the fundamental singularity, and equivalently for the unique solvability of the singular Dirichlet problem for the heat equation. In the measure-theoretical context the criterion

This paper establishes necessary and sufficient condition for the regularity of a characteristic top boundary point of an arbitrary open subset of â„ÂN+1 (N≥2) for the diffusion (or heat) equation. The result implies asymptotic pr
