Title
ON A DEGENERATE NONLOCAL PARABOLIC PROBLEM DESCRIBING INFINITE DIMENSIONAL REPLICATOR DYNAMICS
Abstract
We establish the existence of locally positive weak solutions to the homogeneous Dirichlet problem for u(t) = u Delta u + u integral(Omega) |del u|(2) in bounded domains Omega subset of R-n which arises in game theory. We prove that solutions converge to 0 if the initial mass is small, whereas they undergo blow-up in finite time if the initial mass is large. In particular, it is shown that in this case the blow-up set coincides with (Omega) over bar; i.e., the finite-time blow-up is global.
