A λ-fold G-design is said to be α-resolvable if its blocks can be partitioned into classes such that every class contains each vertex exactly α times. In this paper we study the α- resolvability for λ-fold (K_4-e) -designs and prove that the necessary conditions for their existence are also sufficient, without any exception.

Abstract
A λ-fold G-design is said to be α-resolvable if its blocks can be partitioned into classes such that every class contains each vertex exactly α times. In this paper we study the α- resolvability for λ-fold (K_4-e) -designs and prove that the necessary conditions for their existence are also sufficient, without any exception.File in questo prodotto:
