Global existence, blow-up behavior and numerical simulations for a class of chemotaxis-driven fish-mussel systems

Gnanasekaran Shanmugasundaram, Jitraj Saha

In this work, we investigate a chemotaxis-driven fish--mussel ecosystem model described by a coupled system of partial differential equations subject to homogeneous Neumann boundar…

Global dynamics and diffusion-driven pattern formation in a predator-prey system with two chemicals

Gnanasekaran Shanmugasundaram, Jitraj Saha, Oluwole Daniel Makinde +1

This work analyzes a predator-prey cross-diffusion system coupled with two chemical substances under homogeneous Neumann boundary conditions in a bounded domain Omega subset of R^n…

On the discrete to continuous condensing aggregation equation: A weak convergence approach

Anupama Ghorai, Jitraj Saha

In this article, we study the passage of limits from discrete to continuous condensing aggregation equation which comprises of Oort-Hulst-Safronov (OHS) equation together with inve…

Convergence-rate and error analysis of sectional-volume average method for the collisional breakage equation with multi-dimensional modelling

Prakrati Kushwah, Anupama Ghorai, Jitraj Saha

Recent literature reports two sectional techniques, the finite volume method [Das et al., 2020, SIAM J. Sci. Comput., 42(6): B1570-B1598] and the fixed pivot technique [Kushwah et…

Existence and uniqueness of solutions for coagulation-fragmentation problems with singularity

Jitraj Saha, Jitendra Kumar

In this paper, existence and uniqueness of solutions to a non-linear, initial value problem is studied. In particular, we consider a special type of problem which physically repres…
