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 existence and boundedness in an attraction-repulsion chemotaxis system with nonlocal logistic source and sublinear productions

Gnanasekaran Shanmugasundaram, Nithyadevi Nagarajan

This paper deals with the following attraction-repulsion chemotaxis system with nonlocal logistic source and sublinear productions \[ \left\{ \begin{array}{rrll} &&u_t = d_1 Δu-χ\n…
