Studies of certain classes of functions and its connection with $S$ -embeddedness

Biswajit Mitra, Sanjib Das

We call a function $f$ in $C (X)$ to be hard-bounded if $f$ is bounded on every hard subset, a special kind of closed subset, of $X$ . We call a subset $T$ of $X$ to be $S$ -embedded…

C(X) determines X -- an inherent theory

Biswajit Mitra, Sanjib Das

One of the fundamental problem in rings of continuous function is to extract those spaces for which C(X) determines X, that is to investigate X and Y such that C(X) isomorphic with…

Construction of nearly pseudocompactification

Biswajit Mitra, Sanjib Das

A space is nearly pseudocompact if and only if $υ X \ X$ is dense in $β X \ X$ . If we denote $K = c l_{β X} (υ X \ X)$ , then $δX=X\cup(βX\backslash…

Biswajit Mitra, Sanjib Das

In this paper we have obtained two more characterizations of nearly pseudocompact spaces.

Study of spectrum of certain subrings of a commutative ring with identity

Biswajit Mitra, Debojyoti Chowdhury, Sanjib Das

By a ring we always mean a commutative ring with identity. It is well known that maximal spectrum of $C (X)$ , $C^{*} (X)$ and any intermediate subrings between $C (X)$ and $C^{*} (X)$ are…
