報告摘要：For a given positive integer k, a k-cone C in an Banach space is one that contains a linear subspace of dimension k and no linear subspaces of higher dimension. A convex cone K gives a 1-cone that is the union of K and –K, so a semiflow monotone with respect to a convex cone gives the well known monotone semiflow which has been intensively studied since the seminar series of studies of M. Hirsch. Here we report some recent progress, in collaboration with Lirui Feng and Yi Wang, about the trichotomy of omega-limit sets and generic convergence of semiflows with respect high dimensional k-cone.
