This research note presents a very simple proof of the interesting fact that the set Q of rationale numbers is still countably infinite as is the set of natural and integer numbers. The proof is based on several innovative ideas and neither relies on Cantor’s well-known diagonali...

In a series of weighted Lipschitz algebras \(\left(\Lambda_r\right)_\omega\) of a series of analytic functions on the unit disk, we obtain a comprehensive description of closed ideals that satisfies the following requirement \( \sum_r \frac{\left|f_r(z)-f_r(z+\varepsilon)\right|}...

Accident (whether major or minor) is unexpected and inevitable due to dynamic nature of works, lack of workmanship, and lots of activities in industries. Some occur due to negligence, lack of knowledge or skill, improper handling of tools or equipment, lackadaisical attitudes tow...

This research paper is an introduction to a new type of analogue named as Q -analogue for well-known Baskakov Durrmeyer operators. This new type of analogue is considered as reverse order of -analogue. In this paper, we establish the direct approximation theorem, a weighted appro...

The Lorentz group is a non-compact group. Consequently, it's representations cannot be expected to be equivalent to representations of a unitary group. Actually, they act on a large-component space and a separated small-component space, in some sense analogous to 4-vectors. In co...

A shell C[n, (n - 3)] of size n is a graph obtained by taking (n - 3) concurrent chords in a cycle \(C_n\) on n vertices. Deb and Limaye (2002) have conjectured that all multiple shells are harmonious. The conjecture has prove to be true for uniform double shells, uniform triple...
