摘要:Summary: We introduce and investigate contra-pre-semi-continuous functions. This new class is a superclass of the class of contra-$\beta$-continuous functions and contra-pre-continuous functions.

摘要:Let $X$ be a topological space, $(G,+)$ a topological group and fix a continuous function $\alpha$ from $G$ into $X$. Denote by $N(X,G,\alpha)$ the nearring of all continuous functions from $X$ to $G$ under pointwise addition and where the product $fg$ of two elements $f,g\in N(X...

摘要:The author introduces a new class of generalized closed sets which he calls $\psi$-closed sets. A subset $A$ of a topological space $X$ is said to be $\psi$-closed if $\text{scl}(A) \subseteq U$ whenever $A\subseteq U$ and $U$ is sg-open in $X$. With the help of $\psi$-closed set...

摘要:Summary: We introduce a new class of sets, namely the class of $\delta$-generalized semi-closed (briefly $\delta$-gs-closed) sets by generalizing open sets via $\delta$-semi-closure. This class is properly placed between the classes of $\delta$-sg-closed sets and gs-closed sets. ...
