                                                          报告摘要:A cone of rank-k is a closed set that contains a linear subspace of dimension k and no linear subspaces of higher dimension. In this talk, we focus on smooth monotone systems with respect to k-cones. For k=1, such systems are classical monotone systems, for which the fundamental result is the so-called "Hirsch's generic convergence theorem". We will report in this talk generic behavior of the systems for k(>1)-cones.In particular, a generic Poincare-Bendixson theorem will be presented for high-dimensional autonomous systems, which contains as special case many of the known extensions of the Poincare-Bendixson theorem to dimensions higher than two in the literature. This is a joint work with Lirui Feng and Jianhong Wu.
