Nonpositive curvature: geometric and analytic aspects by J?rgen Jost

By J?rgen Jost

Discusses a variety of geometric and analytic features of non-positive curvature, beginning with Riemannian examples and tension theorems. Treats generalized notions of nonpositive curvature within the experience of Alexandrov and Busemann & the speculation of harmonic maps with values in such areas. Paper.

This quantity makes a speciality of quite a few features of zeta capabilities: a number of zeta values, Ohno’s kinfolk, the Riemann speculation, L-functions, polylogarithms, and their interaction with different disciplines. 11 articles on contemporary advances are written through amazing specialists within the above-mentioned fields. every one article starts off with an introductory survey resulting in the interesting new study advancements entire by way of the participants.
