A phylogeny of biological patterns formed by nonlocal advection

Valeria Giunta, Thomas Hillen, Mark A. Lewis +1

From tumour invasion to cell sorting and animal territoriality, many biological systems rely on nonlocal interactions that drive complex spatial organisation. Partial differential…

Positivity and global existence for nonlocal advection-diffusion models of interacting populations

Valeria Giunta, Thomas Hillen, Mark Lewis +1

In this paper we study a broad class of non-local advection-diffusion models describing the behaviour of an arbitrary number of interacting species, each moving in response to the…

Weakly nonlinear analysis of a two-species non-local advection-diffusion system

Valeria Giunta, Thomas Hillen, Mark A. Lewis +1

Nonlocal interactions are ubiquitous in nature and play a central role in many biological systems. In this paper, we perform a bifurcation analysis of a widely-applicable advection…

Detecting minimum energy states and multi-stability in nonlocal advection-diffusion models for interacting species

Valeria Giunta, Thomas Hillen, Mark A. Lewis +1

Deriving emergent patterns from models of biological processes is a core concern of mathematical biology. In the context of partial differential equations (PDEs), these emergent pa…

Local and Global Existence for Non-local Multi-Species Advection-Diffusion Models

Valeria Giunta, Thomas Hillen, Mark A. Lewis +1

Non-local advection is a key process in a range of biological systems, from cells within individuals to the movement of whole organisms. Consequently, in recent years, there has be…

Global well-posedness and nonlinear stability of a chemotaxis system modeling multiple sclerosis

Laurent Desvillettes, Valeria Giunta, Jeff Morgan +1

We consider a system of reaction-diffusion equations including chemotaxis terms and coming out of the modeling of multiple sclerosis. The global existence of strong solutions to th…
