Dr. Heinz Bauschke of the University of British Columbia Okanagan presents An Invitation to Projection Models as part of the PIMS Distinguished Speaker Series.

Feasibility problems, i.e., finding a solution satisfying certain constraints, are common in mathematics and the natural sciences. If the contraints have simple projectors (nearest point mappings), then one popular approach to these problems is to use the projectors in some algorithmic fashion to approximate a solution. In this talk, I will survey three methods (alternating projections, Dykstra, and Douglas-Rachford), and comment on recent advances and remaining challenges.
