Heat Content Asymptotics of a Riemannian Manifold with Boundary
Abstract Let M be a compact Riemannian manifold with a smooth C ∞ boundary ∂ M . Suppose M has initial temperature 1 at time t = 0 and suppose that ∂ M is kept at temperature 0 for all t > 0. We

Let k ⩾ 3 be an integer. For 0 0 such that no k‐gons overlap if and only if 0 < s ⩽ sk. We derive an explicit formula for sk.
Assessment of the loss of radioactive isotopes from waste solids to the environment. Part I. Background and theory
A report is given of several theoretical expressions based on mass transport phenomena that relate the radioactivity escaping from such solids to diffusion, dissolution processes, surface conditions,
