Generalized quasiconvex set-valued maps

open access: yesJournal of Numerical Analysis and Approximation Theory, 2002
The aim of this paper is to introduce a concept of quasiconvexity for set-valued maps in a general framework, by only considering an abstract convexity structure in the domain and an arbitrary binary relation in the codomain.

On Maximal Clones of Partial Ultrafunctions on a Two-Element Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2016
Class of discrete functions from a finite set $A$ to set of all subsets of A is a natural generalization of the class of many-valued functions on A (k-valued logic functions).

Set-valued functions and selectors [PDF]

open access: yes, 1974
Let S and X be any two sets; then a mapping T which assigns to each point t in S a set T(t) of points in X is called a multifunction (or set-valued function) from S into X. A selector for T is a function f from S into X such that f(t) belongs to the set r(t) for each t.
