Tools for stability analysis of fractional reaction diffusion systems

Sofwah Ahmad, Szymon Cygan, Grzegorz Karch

The linearization principle states that the stability (or instability) of solutions to a suitable linearization of a nonlinear problem implies the stability (or instability) of sol…

Solutions at vacuum and rarefaction waves in pressureless Euler alignment system

Szymon Cygan, Grzegorz Karch

We construct global-in-time weak solutions to the pressureless Euler alignment system posed on the whole line and supplemented with initial conditions, where an initial density is…

Discontinuous stationary solutions to certain reaction-diffusion systems

Szymon Cygan, Anna Marciniak-Czochra, Grzegorz Karch

Systems consisting of a single ordinary differential equation coupled with one reaction-diffusion equation in a bounded domain and with the Neumann boundary conditions are studied…

Stable discontinuous stationary solutions to reaction-diffusion-ODE systems

Szymon Cygan, Grzegorz Karch, Anna Marciniak-Czochra +1

A general system of n ordinary differential equations coupled with one reaction-diffusion equation, considered in a bounded N-dimensional domain, with no-flux boundary condition is…

Instability of all regular stationary solutions to reaction-diffusion-ODE systems

Szymon Cygan, Anna Marciniak-Czochra, Grzegorz Karch +1

A general system of several ordinary differential equations coupled with a reaction-diffusion equation in a bounded domain with zero-flux boundary condition is studied in the conte…

Stability of constant steady states of a chemotaxis model

Szymon Cygan, Grzegorz Karch, Krzysztof Krawczyk +1

The Cauchy problem for the parabolic--elliptic Keller--Segel system in the whole -dimensional space is studied. For this model, every constant is a stationary…

Pattern formation in nonlocal Kondo model

Szymon Cygan

We study a nonlocal evolution equation generalising a model introduced by Shigeru Kondo to explain colour patterns on a skin of a guppy fish. We prove the existence of stationary s…
