A note on almost contra-precontinuous functions

Almost contra-precontinuous functions were introduced by Ekici [7] and recently have been investigated further by Noiri and Popa [13]. The purpose of this note is to develop some new characterizations of almost contra-precontinuous functions and to introduce a new weak form of almost contra-precontinuity, which we call subalmost contraprecontinuity. It is shown that subalmost contra-precontinui...

On Almost Precontinuous Functions

Nasef and Noiri (1997) introduced and investigated the class of almost precontinuous functions. In this paper, we further investigate some properties of these functions.

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.

Almost δ-Precontinuous Multifunctions

In 2001, El-Monsef and Nasef have introduced γ-continuous multifunctions and in 2004, Park, Lee and Son have studied δ-precontinuous multifunctions. The purpose of this paper is to generalize some types of continuous multifunctions. In this paper, the notion of almost δ-precontinuous multifunctions is studied. Basic properties, characterizations and relationships of almost δ-precontinuous multi...

On Θ-precontinuous Functions

We introduce a new class of functions called θ-precontinuous functions which is contained in the class of weakly precontinuous (or almost weakly continuous) functions and contains the class of almost precontinuous functions. It is shown that the θprecontinuous image of a p-closed space is quasi H-closed. 2000 Mathematics Subject Classification. 54C08.
