By Aram V. Arutyunov,Valeri Obukhovskii

This textbook is dedicated to a compressed and self-contained exposition of 2 very important elements of up to date arithmetic: convex and set-valued research. within the first half, houses of convex units, the speculation of separation, convex features and their differentiability, homes of convex cones in finite- and infinite-dimensional areas are mentioned. the second one half covers a few vital elements of set-valued research. There the houses of the Hausdorff metric and numerous continuity strategies of set-valued maps are thought of. the nice cognizance is paid additionally to measurable set-valued services, non-stop, Lipschitz and a few precise different types of decisions, fastened element and accident theorems, masking set-valued maps, topological measure idea and differential inclusions.

Part I: Convex analysis
Convex units and their properties
The convex hull of a collection. the inner of convex sets
The affine hull of units. The relative inside of convex sets
Separation theorems for convex sets
Convex functions
Closedness, boundedness, continuity, and Lipschitz estate of convex functions
Conjugate functions
Support functions
Differentiability of convex services and the subdifferential
Convex cones
A little extra approximately convex cones in infinite-dimensional spaces
A challenge of linear programming
More approximately convex units and convex hulls
Part II: Set-valued analysis
Introduction to the speculation of topological and metric spaces
The Hausdorff metric and the space among sets
Some superb homes of the Hausdorff metric
Set-valued maps. top semicontinuous and decrease semicontinuous set-valued maps
A base of topology of the spaceHc(X)
Measurable set-valued maps. Measurable choices and measurable selection theorems
The superposition set-valued operator
The Michael theorem and non-stop decisions. Lipschitz choices. Single-valued approximations
Special choices of set-valued maps
Differential inclusions
Fixed issues and coincidences of maps in metric spaces
