Handbook of the Geometry of Banach Spaces: Volume 1

The instruction manual provides an outline of such a lot features of contemporary Banach house concept and its functions. The updated surveys, authored through prime examine employees within the region, are written to be available to a large viewers. as well as proposing the cutting-edge of Banach area concept, the surveys speak about the relation of the topic with such parts as harmonic research, complicated research, classical convexity, likelihood idea, operator thought, combinatorics, common sense, geometric degree concept, and partial differential equations.

Geometry IV: Non-regular Riemannian Geometry

The booklet includes a survey of analysis on non-regular Riemannian geome­ try out, conducted as a rule through Soviet authors. the start of this course oc­ curred within the works of A. D. Aleksandrov at the intrinsic geometry of convex surfaces. For an arbitrary floor F, as is understood, all these recommendations that may be outlined and proof that may be demonstrated via measuring the lengths of curves at the floor relate to intrinsic geometry.

Geometry Over Nonclosed Fields

In line with the Simons Symposia held in 2015, the lawsuits during this quantity specialize in rational curves on higher-dimensional algebraic types and functions of the idea of curves to mathematics difficulties. there was major growth during this box with significant new effects, that have given new impetus to the examine of rational curves and areas of rational curves on K3 surfaces and their higher-dimensional generalizations.
