Homeomorphism mapping
WebThe meaning of HOMEOMORPHISM is a function that is a one-to-one mapping between sets such that both the function and its inverse are continuous and that in topology exists … Web4. Circle Homeomorphisms 4.1. Rotation numbers. Let f: S1 → S1 be an orientation preserving homeomorphism. Let π: R → S1 be the map π(t) = exp(2πit). Lemma 4.1. There is a continuous map F: R → R such that (i) πF = fπ; (ii) F is monotone increasing; (ii) F −id is periodic with period 1. Moreover, any two such maps differ by an integer

WebHomeomorphism Mapping Based Neural Networks for Finite Time Constraint Control of a Class of Nonaffine Pure-Feedback Nonlinear Systems: This paper proposes a new scheme for solving finite time neural networks adaptive tracking control issue for the nonaffine pure-feedback nonlinear system. A homeomorphism is simultaneously an open mapping and a closed mapping; that is, it maps open sets to open sets and closed sets to closed sets. Every self-homeomorphism in can be extended to a self-homeomorphism of the whole disk (Alexander's trick).
