TITLE:   Fading absorption in semilinear elliptic and parabolic
         equations
 
PLACE:   Room 814, Amado Mathematics Building, Technion
 
TIME:    14:30
 
ABSTRACT: We study Dirichlet and Cauchy-Dirichlet problems with
singular nonnegative data for semilinear elliptic and parabolic
equations of diffusion-absorption type with absorption potential,
degenerating on some manifolds in the closure of the domain under
consideration. We investigate existence of nonnegative "large" and
very singular (more singular, than corresponding fundamental)
solutions in dependence of character of degeneration of the potential
and find some sufficient and necessary conditions of existence. In
some model situation we find criterium of existence if such a
solution, which has form of some Dini-like condition.
 
Results of joint investigations with M. Marcus, L. Veron.
