Abstract

We consider the problem of making the notion of dynamic labeled 2-structure even more dynamic by allowing the domain of a dynamic labeled 2-structure to vary by either adding new elements or deleting some elements. To this aim we study in the framework of dynamic labeled 2-structures the operation of disjoint union (in combination with group-theoretic operations induced by selectors) and a more general operation of amalgamated union.
