By Werner Ballmann

Singular areas with top curvature bounds and, specifically, areas of nonpositive curvature, were of curiosity in lots of fields, together with geometric (and combinatorial) crew conception, topology, dynamical platforms and likelihood thought. within the first chapters of the e-book, a concise advent into those areas is given, culminating within the Hadamard-Cartan theorem and the dialogue of the right boundary at infinity for easily attached whole areas of nonpositive curvature. within the 3rd bankruptcy, qualitative homes of the geodesic circulate on geodesically whole areas of nonpositive curvature are mentioned, as are random walks on teams of isometries of nonpositively curved areas. the most classification of areas thought of can be accurately complementary to symmetric areas of upper rank and Euclidean structures of size not less than (Rank tension conjecture). within the tender case, this can be recognized and is the content material of the Rank tension theorem. An up-to-date model of the evidence of the latter theorem (in the sleek case) is gifted in bankruptcy IV of the publication. This bankruptcy includes additionally a quick advent into the geometry of the unit tangent package of a Riemannian manifold and the elemental proof in regards to the geodesic circulate. In an appendix via Misha Brin, a self-contained and brief evidence of the ergodicity of the geodesic circulate of a compact Riemannian manifold of adverse curvature is given. The evidence is uncomplicated and may be available to the non-specialist. a number of the crucial positive factors and difficulties of the ergodic conception of tender dynamical structures are mentioned, and the appendix can function an advent into this idea.

By Frédéric Cao

In photograph processing, "motions via curvature" supply a good solution to soft curves representing the boundaries of gadgets. In one of these movement, every one element of the curve strikes, at any speedy, with a regular speed equivalent to a functionality of the curvature at this aspect. This ebook is a rigorous and self-contained exposition of the concepts of  "motion by way of curvature". The method is axiomatic and formulated by way of geometric invariance with appreciate to the location of the observer. this is often translated into mathematical phrases, and the writer develops the procedure of Olver, Sapiro and Tannenbaum, which classifies all curve evolution equations. He then attracts a whole parallel with one other axiomatic method utilizing level-set tools: this ends up in generalized curvature motions. ultimately, novel, and intensely exact, numerical schemes are proposed permitting one to compute the answer of hugely degenerate evolution equations in a totally invariant manner. The convergence of this scheme can also be proved.

By Silouanos Brazitikos, Apostolos Giannopoulos, Petros Valettas

The examine of high-dimensional convex our bodies from a geometrical and analytic perspective, with an emphasis at the dependence of assorted parameters at the measurement stands on the intersection of classical convex geometry and the neighborhood concept of Banach areas. it's also heavily associated with many different fields, reminiscent of chance conception, partial differential equations, Riemannian geometry, harmonic research and combinatorics. it's now understood that the convexity assumption forces many of the quantity of a high-dimensional convex physique to be centred in a few canonical approach and the most query is whether or not, less than a few common normalization, the reply to many primary questions may be self sufficient of the measurement. the purpose of this ebook is to introduce a few recognized questions concerning the distribution of quantity in high-dimensional convex our bodies, that are precisely of this nature: between them are the cutting challenge, the skinny shell conjecture and the Kannan-Lovász-Simonovits conjecture. This ebook presents a self-contained and recent account of the growth that has been made within the final fifteen years.
