Analysis in spaces with no a priori smooth structure has progressed to include concepts from
the first order calculus. In particular, there have been important advances in understanding …

We exhibit a rigidity property of the simple groups and F-20 4 which implies Mostow rigidity.
This property does not extend to Ø (n, 1) and U(n,1).Theproofreliesonquasiconformaltheoryappli …

This book proposes new notions of coherent geometric structure. Fractal patterns have
emerged in many contexts, but what exactly is a" pattern" and what is not? How can one …

We give a definition for the class of Sobolev functions from a metric measure space into a
Banach space. We give various characterizations of Sobolev classes and study the absolute …
