O Botchkarev,S Tripakis - Springer Berlin Heidelberg 被引量: 310发表: 2000年 On duality and endomorphisms of lattices of closed convex sets The class of closed convex sets in is a lattice with respect to the operations of intersections and closed convex hulls of unions. We completely classify...
Mathematical sets are collections of objects or concepts that can be joined together to become mathematical building blocks. Learn about mathematical sets and understand their function in mathematics. Explore the roles of elements, intersections, and unions in mathematical sets. Understanding Sets A set...
In this chapter, the properties of generalized unions and intersections of sets are also discussed. The chapter presents the equations of generalized De Morgan laws. These equations state that the complement of a generalized union equals the generalized intersection of the complements and that the ...
such that the union of every proper subfamily of F is acyclic; and (2) Let F = {X_i}_(i=0)~m, m> 1) be a family of open or closed acyclic sets in R~2 such that the union of every two elements of F is path-connected and the union of every three elements of F is ...
R-unions and R-intersections of T-external (Iexternal, F-external) neutrosophic cubic sets are considered. Examples to show that the R-intersection and R-union of Texternal (I-external, F-external) neutrosophic cubic sets may not be a T-external (I-external, F-external) neutrosophic cubic...
We prove several results which enable us to simplify constructing the type-2 membership functions for intersections and unions of fuzzy sets of operands. We check that de Morgan's laws hold for these two operations with fuzzy sets of operands. As far as the two operations on crisp sets are ...

Unions of increasing and intersections of decreasing sequences of convex sets We prove that a convex set C is a polytope if and only if C is not the union of any strictly increasing sequence of convex sets. In addition, we attempt ... V Klee - 《Israel Journal of Mathematics》 被引量...
