Propagation of weak singularities on characteristic surfaces of non-constant multiplicity
Professor Zbigniew Peradzyński (for friends simply Zbyszek) is a recipient of the Steinhaus Prize in the field of Applied Mathematics, in year 2011. According to the jury's verdict, the prize has been awarded for Zbyszek's overall scientific activity, in particular for his contribution to the theoretical research of ion thrusters and his work on the superfluid helium theory. The verdict is based on papers, which are enumerated in the references. Zbyszek first showed his interest in space journeys...
PhD studies in Mathematics and Natural Science, called MISDoMP, have been conducted within the College of MISMaP UW since 2008. The College itself was formed in 2001 by seven UW faculties: Biology, Chemistry, Physics, Geography and Regional Studies, Geology, Mathematics, Informatics and Mechanics as well as Psychology. This inter-faculty study programme offers a wide range of new opportunities for open-minded students whose broad interests go beyond the beaten paths of traditional education. This...

In this note we analyze equilibria of static Stefan type problems with crystalline/singular weighted mean curvature in the plane. Our main goal is to improve the meaning of variational solutions so that their properties allow us to call them almost classical solutions. The idea of our approach is based on a new definition of a composition of multivalued functions.
