He gives a talk on the entitled "Augmented Lagrangian preconditioner for linear stability analysis of incompressible fluid flows".
The efficient iterative resolution of saddle-point problem arising when addressing the stability analysis of incompressible flows is addressed using a class of preconditioner, the so-called Augmented Lagrangian preconditioner. It has been implemented with the FreeFem++ software, in a parallel computing environment, thanks to an interface with the PETSc library, developed by P. Jolivet.
