We discuss sixth order accurate 9-point compact 2- and 3-phase block alternating group explicit (block-AGE) iteration methods for computing 2D Helmholtz equation. We use Dirichlet boundary conditions and no fictitious points are involved outside the

In this piece of work, a family of compact implicit numerical algorithms for (∂u/∂n) of order of accuracy six are proposed on a 9- and 19-point compact cell for two- and three- dimensional Poisson equations ∆2u=f which are quite often useful in

In literature, several models which can handle uncertainty in datasets have been introduced. Fuzzy set introduced by Zadeh in 1965, is one of the earliest such models and Atanassov generalised it by introducing the notion of Intuitionistic fuzzy sets

A spline-in-compression method, implicit in nature, for computing numerical solution of second order nonlinear initial-value problems (IVPs) on a mesh not necessarily equidistant is discussed. The proposed estimation has been derived directly from co

This study suggests a novel three-level implicit half-step scheme of order two and four in time and space direction respectively, utilizing an unequal grid for the approximation of 2D quasi-linear hyperbolic partial differential equations on an unequ

This paper reports a new fourth order Finite Difference Method (FDM) in exponential form for two-dimensional quasilinear boundary value problem of elliptic type (BVPE) with variant solution domain. Further, this discretization is extended to solve th

This article presents a new approximation of order four in exponential form for two-dimensional (2D) quasilinear partial differential equation (PDE) of elliptic form with solution domain being irrational. It is further extended for application to a s

This article presents the results of the analysis of the pottery from the recently excavated site at Mahurjhari in central India. In doing so, it also proposes a new way of looking at archaeological ceramics in South Asia. Here, archaeological cerami

In this paper, we propose a new three-level implicit nine point compact finite difference formulation of O(k2 + h4) based on non-polynomial tension spline approximation in r-direction and finite difference approximation in t-direction for the numeric
