Given real valued functions f defined on E and g defined on R^n\, the classical Obstacle Problem asks for a minimizer of the Dirich let energy subject to the following two constraints: (1) F = f on E and (2 ) F >= g on R^n. In this talk\, we will discuss how to use extension theor y to construct (almost) solutions directly. We will also explain several r ecent results that will help lay the foundation for building a complete th eory revolving around the belief that any variational problems that can be solved using PDE theory can also be dealt with using extension theory.\n DTSTART:20181026T180000Z DTEND:20181026T190000Z LOCATION:Room 1120\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:K.
