We establish weak–strong uniqueness and stability properties of renormalized solutions to a class energy-reaction-diffusion systems. The systems considered are motivated by thermodynamically consistent models, their formal entropy structure allows us use as key tool suitably adjusted relative method. principle holds for dissipative solutions, which in addition the formulation obey suitable diss...

A reaction-diffusion system with mass conservation modelling cell polarity is considered. range of the parameters found where solution converges exponentially to constant equilibrium and $\omega$-limit set spatially homogeneous, containing stationary as well possible homogeneous orbits.
