In this work, we present a rigorous mathematical scheme for the derivation of the sth-order
perturbative corrections to the solution to a one-dimensional harmonic oscillator perturbed …

Shear waves find applications in several branches of science, such as geophysics, earth
science, medical science etc. The Haar wavelet (HW) scheme is employed to solve the …

This paper deals with the partial solution of the energy-eigenvalue problem for one-
dimensional Schr\" odinger operators of the form $ H_N= X_0^ 2+ V_N $, where $ V_N …

This work deals with the development of an efficient interpolating wavelet collocation
scheme for obtaining highly accurate eigenstates of Sturm–Liouville problem with a view to …

Most of the physical systems are nonlinear in nature, and they execute vibrations which is a
deviation from the exactly solvable harmonic oscillator (HO) due to the presence of …
