Sharp Estimates on Coefficient functionals of Ozaki close-to-convex functions
Sushil Kumar, Rakesh Kumar pandey, Pratima Rai
The goal of this manuscript to establish the best possible estimate on coefficient functionals like Hermitian-Toeplitz determinant of secoend order involving logarithmic coefficien…
Sharp bounds on Coefficient functionals of certain Sakaguchi functions
Sushil Kumar, Rakesh Kumar Pandey, Pratima Rai
We determine sharp bounds on some Hankel determinants involving initial coefficients, inverse coefficients, and logarithmic inverse coefficients for two subclasses of Sakaguchi fun…
Robust numerical schemes for singularly perturbed delay parabolic convection diffusion problems with degenerate coefficient
Pratima Rai, Swati yadav
This article studies a dirichlet boundary value problem for singularly perturbed time delay convection diffusion equation with degenerate coefficient. A priori explicit bounds are…
A higher order numerical scheme for singularly perturbed parabolic turning point problems exhibiting twin boundary layers
Swati yadav, Pratima Rai
In this article, a parameter-uniform numerical method is presented to solve one-dimensional singularly perturbed parabolic convection-diffusion turning point problem exhibiting two…
