Contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions

The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.

Complexity: Order contra Chaos

A concise commentary on observing and modeling complexity within the framework of dynamical systems, information, and computation theories. Deterministic chaos, randomness, order, predictability, uncertainty, and complexity are contrasted. The descriptive abstraction of state is seen to be a natural extension of the symbolization necessary for language and of the number concept. Philosophical c...

Contra-e-Continuous Functions

In 2008, E. Ekici [13] introduced a new class of generalized open sets in a topological space called e-open sets. M. Ozkoc and G Aslim [26], in their recent paper (Bull. Korean Math. Soc. 47 (2010), No. 5, pp. 10251036), initiated two strong forms of e-open sets for the study of stronglyθ-e-continuous functions. J. Dontchev [8] introduced the notion of contra continuous functions. In this paper...
