Attractors and Chain Recurrence for Semigroup Actions
TL;DR: In this paper, the complementary repeller of an attractor is defined and characterized in terms of attractors for the set of chain recurrent points in a topological space M. The concept depends on a family of subsets of a semigroup.
Journal ArticleDOI
Finest Morse Decompositions for Semigroup Actions on Fiber Bundles
TL;DR: In this article, the authors studied the Morse decomposition for semigroup actions on principal bundles and their associated bundles, considering their projections onto the base space and their intersections with the fibers.
Journal ArticleDOI
On limit behavior of semigroup actions on noncompact spaces
TL;DR: In this paper, the authors extend Conley's characterization of chain recurrence in terms of attractors from the setting of flows on compact metric spaces to any topological space and show how the limit behavior can be studied in arbitrary topological spaces by using powerful tools such as the Stone-Čech compactification and shadowing semigroups.
Journal ArticleDOI
Prolongational limit sets of control systems
TL;DR: In this article, the authors introduce the notions of prolongations and prolongational limit sets of control systems, and show how these limit sets play in studying recursive and dispersive control systems.
