Handbook of the Geometry of Banach Spaces: Volume 1

The guide provides an summary of so much facets of recent Banach house idea and its purposes. The up to date surveys, authored through top learn employees within the zone, are written to be obtainable to a large viewers. as well as offering the state-of-the-art of Banach house thought, the surveys talk about the relation of the topic with such components as harmonic research, complicated research, classical convexity, chance conception, operator concept, combinatorics, common sense, geometric degree conception, and partial differential equations.

Geometry IV: Non-regular Riemannian Geometry

The ebook features a survey of analysis on non-regular Riemannian geome­ test, performed regularly by means of Soviet authors. the start of this path 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 innovations that may be outlined and evidence that may be demonstrated by way of 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 concentrate on 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 research of rational curves and areas of rational curves on K3 surfaces and their higher-dimensional generalizations.
