Abstract: | The largest class of multivalued systems satisfying the module-like axioms is the Hv-module. Hv-modules first were introduced by Vougiouklis. In this paper we define weak equality between two subsets of an Hv-module and introduced the notion of exact sequences of Hv-modules. Also some results on the weak equality and exact sequences are given. |
