Wojciech Zajaczokowski, Università di Varsavia

venerdì 23 maggio 2003 alle ore 15:00, Aula Seminari MOX – 6° piano dip. di MatematicaABSTRACTIn this seminar we discuss existence and uniqueness of global regular solutions to the Navier-Stokes equations in cylindrical and axially symmetric domains. We assume the slip boundary conditions. We prove existence of such solutions which are close to the axially symmetric solutions. The existence will be shown in two steps. First we show how to prove existence of local solutions with large existence time which magnitude increases if initial data are more closed to the initial data for the axially symmetric solution. Next assuming some decay estimates for the external force we will be able to show that the local solution can be prolonged step by step up to infinity**Il sistema solare: un orologio perfetto o una Babele ben mascherata?

mercoledì 21 maggio 2003 alle ore 12:30, aula consiglio VII piano**The classical limit of the relativistic Vlasov-Maxwell system in two space dimensions**

Hayoung Lee, Max Planck Institute for Gravitational Physics

giovedì 15 maggio 2003 alle ore 16:15, Aula seminari III pianoABSTRACTThe motion of a collisionless plasma is modeled by the Vlasov-Maxwell system. Here the speed of light, c, appears as a parameter. First we study the existence of classical solutions of the relativistic Vlasov-Maxwell system with smooth initial data, on a time interval independent of c. Then we show that solutions of the relativistic Vlasov-Maxwell system converge pointwise to solutions of the non relativistic Vlasov-Poisson system as c tends to infinity, at the asymptotic rate of 1/c.**Quasistationary Penrose-Fife Model with Neumann Boundary Conditions.**

Anastasia Klepatcheva, Politecnico di Milano

giovedì 15 maggio 2003 alle ore 17:15, Aula seminari III piano, Dip. di MatematicaABSTRACTWe study the problem of the existence of a global solution to the quasistationary phase field model of the Penrose-Fife type.

We prove the existence of approximate solutions and obtain a priori estimate.
