Principal eigenvalues and asymptotic behavior for the weighted -Laplacian with Robin boundary conditions on exterior domains
Subha Pal, Sarath Sasi
The spectral theory of the p-Laplacian is well developed for classical Dirichlet and Neumann boundary conditions, but the transitional Robin regime on exterior domains remains larg…

Critical perturbation sizes for preserving decay rates in solutions of perturbed nonlinear differential equations
John A. D. Appleby, Subham Pal
This paper develops necessary and sufficient conditions for the preservation of asymptotic convergence rates of deterministically and stochastically perturbed ordinary differential…

Two-phase stratified MHD flows in wide rectangular ducts: analytical and numerical solutions
Ilya Barmak, Subham Pal, Alexander Gelfgat +1
This study explores the effects of a non-conductive gas layer flowing concurrently with a conductive liquid on the two-phase flow characteristics in wide horizontal ducts under a c…
