Normal form of Turing–Turing bifurcation for the diffusive Bazykin system with prey-taxis

International Journal of Biomathematics
In this paper, we introduce prey-taxis to the diffusive Bazykin system and study the codimension-two Turing–Turing bifurcation of this modified system. For the local system, i.e. without diffusion terms and the prey-taxis term, we investigate the stability of the unique positive equilibrium.

On the convective nature of the instability of a front undergoing a supercritical Turing bifurcation

Mathematics and Computers in Simulation, 2009
The author studies some stability questions related to the parabolic system \[ \begin{aligned} & \partial_tu_1=\partial^2_xu_1+\tfrac12(u_1-c)(1-u^2)+\gamma_1u^2_2\\ & \partial_tu_2=-(1+\partial^2_x)^2u_2+\alpha u_2-u^3_2-\gamma_2u_2(1+u_1)\end{aligned}\tag{1} \] already considered in [(*) \textit{A. Ghazaryan} and \textit{B. Sandstede}, SIAM J.
