Rescaling method for blow-up solutions of nonlinear wave equations

Mondher Benjemaa, Aida Jrajria, Hatem Zaag

We develop a hybrid scheme based on a finite difference scheme and a rescaling technique to approximate the solution of nonlinear wave equation. In order to numerically reproduce t…

Construction of type I-Log blowup for the Keller-Segel system in dimensions and

V. T. Nguyen, N. Nouaili, H. Zaag

We construct finite time blowup solutions to the parabolic-elliptic Keller-Segel system $\partial_t u = Δu - \nabla \cdot (u \nabla \mathcal{K}_u), \quad -Δ\mathcal{K}_u = u \quad…

The blow-up rate for a loglog non-scaling invariant semilinear wave equation

Tristan Roy, Hatem Zaag

We consider blow-up solutions of a semilinear wave equation with a loglog perturbation of the power nonlinearity in the subconformal case, and show that the blow-up rate is given b…

Unsupervised physics-informed neural network in reaction-diffusion biology models (Ulcerative colitis and Crohn's disease cases) A preliminary study

Ahmed Rebai, Louay Boukhris, Radhi Toujani +6

We propose to explore the potential of physics-informed neural networks (PINNs) in solving a class of partial differential equations (PDEs) used to model the propagation of chronic…
