This paper derives approximate ‘sunset’ similarity solutions for receding plane strain and radially symmetric hydraulic fractures in permeable elastic media close to the point of closure. Local analysis is used show that a fracture has linear aperture asymptote $\hat {w}\sim \hat {s}$ tip, where distance from front. Due regularity asymptote, it possible determine form power series expansions, w...

This paper continues the study of a new class of repeated games with imperfect public monitoring launched by Sannikov (2007). I provide a new characterization of self-generating sets for a class of games in continuous time and Brownian information. This new characterization relies on partial differential equation techniques. Our approach gives a geometric characterization of the set of perfect ...
