Phenotype switching in chemotaxis aggregation models controls the spontaneous emergence of large densities

Kevin J Painter, Michael Winkler

We consider a phenotype-switching chemotaxis model for aggregation, in which a chemotactic population is capable of switching back and forth between a chemotaxing state (performing…

A quantitative strong parabolic maximum principle and application to a taxis-type migration-consumption model involving signal-dependent degenerate diffusion

Michael Winkler

The taxis-type migration-consumption model accounting for signal-dependent motilities, as given by \[ u_t = Δ\big(uϕ(v)\big), v_t = Δv-uv, \qquad (*) \] is considered for suitably…

Weak solutions to triangular cross diffusion systems modeling chemotaxis with local sensing

Laurent Desvillettes, Philippe Laurençot, Ariane Trescases +1

New estimates and global existence results are provided for a class of systems of cross diffusion equations arising from the modeling of chemotaxis with local sensing, possibly fea…

Global existence in reaction-diffusion systems with mass control under relaxed assumptions merely referring to cross-absorptive effects

Johannes Lankeit, Michael Winkler

We introduce a generalized concept of solutions for reaction-diffusion systems and prove their global existence. The only restriction on the reaction function beyond regularity, qu…

A double critical mass phenomenon in a no-flux-Dirichlet Keller-Segel system

Jan Fuhrmann, Johannes Lankeit, Michael Winkler

Derived from a biophysical model for the motion of a crawling cell, the system \[(*)~\begin{cases}u_t=Δu-\nabla\cdot(u\nabla v)\\0=Δv-kv+u\end{cases}\] is investigated in a finite…

A critical blow-up exponent for flux limitation in a Keller-Segel system

Michael Winkler

The parabolic-elliptic cross-diffusion system \[ \left\{ \begin{array}{l} u_t = Δu - \nabla \cdot \Big(uf(|\nabla v|^2) \nabla v \Big), \\[1mm] 0 = Δv - μ+ u, \qquad \int_Ωv=0, \qq…
