ALOP-Colloquium with Prof. John Pearson
20. November 2017 / 16:00 - 18:00
On Monday, November 20, 2017, at 16:00 Prof. John Pearson of School of Mathematics, The University of Edinburgh will join the ALOP-Colloquium and present his recent work entitled
Four Perspectives on Preconditioning PDE-Constrained Optimization Problems
PDE-constrained optimization problems have a wide range of applications across numerical mathematics and applied science, so it is important to develop fast and feasible methods to solve such problems. We employ preconditioned iterative methods to tackle the large and sparse matrix systems that arise from their discretization, and consider a range of issues related to these solvers. In particular, we discuss applications of reaction-diffusion control problems in mathematical biology, strategies for handling additional box constraints on the PDE variables, approaches for problems involving fractional derivatives, and deferred correction methods for time-dependent problems.
The presentation will take place in HS9
Please join us for coffee at 15:45 in E10
