1 A problem or scrambled setCHAOTIC behavior is a manifestation of complexity of nonlinear dynamical systems. Since theobjects, methods, aims, or emphases of study are distinct, there are some variant definitionsof ch...

Let P be a pseudo-arc in 2-sphere S2. A homeomorphism h : P →→ P is called essentially extendable iff there exists an imbedding φ:P → S2 such that the homeomorphism φ hφ-1: φ(...
Kerékjártó[1, pp. 224—226] showed that every periodic self-homeomorphism of a disk is topologically conjugate to either a rotation or a reflection, which is restated by Brechner in Ref. [2]. According to this conc...
In this report, we shall introduce the concept called the stratification-preserving fuzzy order homomorphism and discuss its structure, and then use it to give another definition of fuzzy homeomorphism. This definitio...
