چکیده
Class field theory furnishes an intrinsic description of the abelian extensions of a number field that is in many cases not of an immediate algorithmic nature. We outline the algorithms available for the explicit computation of such extensions.

We obtain a sharp local well-posedness result for the Gradient Nonlinear Wave Equation on a nonsmooth curved background. In the process we introduce variable coefficient versions of Bourgain’s X spaces, and use a trilinear multiscale wave packet decomposition in order to prove a key trilinear estimate.

We consider a class of compacta X such that the maps from X onto metric compacta define an Aronszajn tree of closed subsets of X.
