Determining nodes for semilinear parabolic equations. (arXiv:0910.0595v1 [math.AP])

We discuss the uniqueness of the equilibria of time-global solutions of
general semilinear parabolic equations by a finite set of values of these
solutions. More precisely, if the asymptotic behaviour of a time-global
solution is known on an appropriate finite set, then the asymptotic behaviour
of a time-global solution itself is entirely determined in a domain.
