Josef Stefan was a professor of physics at the University of Vienna between 1863 and 1893. During his time in Vienna he was a fruitful researcher in many scientific fields, but he is best known for his work in heat transfer. He was a gifted experimentalist and theoretician who made contributions to conduction, convection and radiation heat transfer. Stefan was the first to accurately measure th...
Asymptotic behavior of solutions to the Stefan problem with a kinetic condition at the free boundary
Abstract We examine travelling wave solutions of the reaction–diffusion equation, ? t u =</mml...

Using antigen-specific human T lymphocytes as immunogens, it has been possible to generate monoclonal antibodies against clonally unique surface determinants expressed on a novel class of 90-kdalton Ti molecules. Each surface Ti molecule exists as a heterodimer comprised of a covalently linked 49-kdalton aand 43-kdalton 0-chain and, in addition, is membrane-associated with the 20 / 25-kdalton T...
For a linear transport equation in one space dimension with speeds in a compact interval and a general symmetric kernel for the change of velocity a problem with free boundary (Stefan problem) is stated. The case of constant speed corresponds to a Stefan problem for the damped wave equation (telegraphers equation). Existence and uniqueness of the free boundary is shown, and the connection to th...
The Chen groups of a finitely-presented group G are the lower central series quotients of its maximal metabelian quotient, G/G′′. The direct sum of the Chen groups is a graded Lie algebra, with bracket induced by the group commutator. If G is the fundamental group of a formal space, we give an analog of a basic result of D. Sullivan, by showing that the rational Chen Lie algebra of G is isomorp...
