Abstract
DS-diagram and flow spine are good tools for studying 3-manifolds ([5], [8]). In this paper, we introduce the concept of generalized DS-diagram and study its properties. We define two types of moves that change generalized DS-diagrams but do not change their associated manifolds. We prove that any two generalized DS-diagrams such that their associated manifolds are homeomorphic to each other can be deformed into each other by a finite sequence of moves of the types.
