In this paper, the stability of finite difference methods for time-dependent Schrodinger equation with Dirichlet boundary conditions on a staggered mesh was considered with explicit and implicit discretization. Using the matrix representation for the numerical algorithm, it is sh...

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...

Two-party channel setting has been a choice study-setting for trade credit. This work considers a three-member channel setting using Stackelberg game theory. The study considers the manufacturer as the channel leader, with the distributor as the first follower, and the retailer a...

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...
