Error analysis of a backward Euler positive preserving stabilized scheme for a Chemotaxis system
Panagiotis Chatzipantelidis, Christos Pervolianakis
For a Keller-Segel model for chemotaxis in two spatial dimensions we consider a modification of a positivity preserving fully discrete scheme using a local extremum diminishing flu…

Numerical analysis of a stabilized scheme for an optimal control problem governed by a parabolic convection--diffusion equation
Christos Pervolianakis
We consider an optimal control problem on a bounded domain governed by a parabolic convection--diffusion--reaction equation with pointwise control constrai…

Error analysis of an Algebraic Flux Correction Scheme for a nonlinear Scalar Conservation Law Using SSP-RK2
Christos Pervolianakis
We consider a scalar conservation law with linear and nonlinear flux function on a bounded domain with Lipschitz boundary We discretize the spatial…
