On Strongly g*-continuous Maps and Pasting Lemma in Topological Spaces
The objective of the present paper is to introduce new classes of functions called Strongly g∗-continuous maps .We obtain some characterizations of these classes and several properties are studied.Also we prove Pasting lemma for Strongly g∗-continuous maps.
Strongly (λ, θ)-continuous functions
In the paper, we introduce and investigate basic properties of a new class of functions between topological spaces called strongly (λ, θ)-continuous functions which is stronger than λ-continuous functions.
Normed units in abelian group rings
We compute explicitly the isomorphic structure of the normalized unit group of an abelian group ring under some minimal natural restrictions on the group basis and the coefficient ring. This enlarges affirmations due to Chatzidakis-Pappas (J. London Math. Soc., 1991) and Mollov (Publ. Math. Debrecen, 1971).
