Title: On the Caginalp phase-field system based on the Cattaneo law with 
nonlinear coupling



Abstract: Caginalp phase-field model describes the behaviour of certain 
materials in their stages of melting and solidification. In this talk, 
we will start by motivating the use of Cattaneo's law and give a 
rigorous derivation of our model. We then address mathematical problems 
of existence and uniqueness, dissipativity and spatial behaviour in a 
semi-infinite cylinder. We finally give the convergence for a iterative 
scheme of fractional steps type associated to the phase-field transition 
system as an illustration regarding numerical approach.
