  We prove that every combinatorial dynamical system in the sense of Forman,
defined on a family of simplices of a simplicial complex, gives rise to a
multivalued dynamical system F on the geometric realization of the simplicial
complex. Moreover, F may be chosen in such a way that the isolated invariant
sets, Conley indices, Morse decompositions, and Conley-Morse graphs of the two
dynamical systems are in one-to-one correspondence.
