Abstract:
For a given semilinear parabolic equation with polynomial
nonlinearity, many solutions blow up in finite time. For a certain
class of these equations, we show that some of the solutions which do
not blow up actually tend to equilibria. The characterizing property
of such solutions is a finite energy constraint, which comes about
from the fact that this class of equations can be written as the flow
of the L^2 gradient of a certain functional.
