An improved Haar wavelet quasilinearization technique for a class of generalized Burger's equation
Amit K. Verma, Mukesh Rawani
Solving Burgers' equation always poses challenge to researchers as for small values of viscosity the analytical solution breaks down. Here we propose to compute numerical solution…

Amit K. Verma, Narendra Kumar, Diksha Tiwari
In this work we present Haar wavelet collocation method and solve the following class of system of Lane-Emden equation defined as \begin{eqnarray*} -(t^{k_1} y'(t))'=t^{-ω_1} f_1(t…
Haar wavelets collocation on a class of Emden-Fowler equation via Newton's quasilinearization and Newton-Raphson techniques
Amit Kumar Verma, Narendra Kumar
In this paper we have considered generalized Emden-Fowler equation, \begin{equation*} y''(t)+σt^γy^β(t)=0, ~~~~~~~~t \in ]0,1[ \end{equation*} subject to the following boundary con…

On some computational aspects of Hermite wavelets on a class of SBVPs arising in exothermic reactions
Amit K. Verma, Diksha Tiwari
We propose a new class of SBVPs which deals with exothermic reactions. We also propose four computationally stable methods to solve singular nonlinear BVPs by using Hermite wavelet…
