It is shown to be undecidable whether an c-free finite substitution and a two-state simple E-free ngsm are equivalent on {a, b}\*. Consequently, the state-minimization of such ngsm's and the nonterminal-minimization of linear grammars having two nonterminals are undecidable. Applications to some ot

Certain problems involving the coloring the edges or vertices of infinite graphs are shown to be undecidable. In particular, let G and H be finite 3-connected graphs, or triangles. Then a doubly-periodic infinite graph F is constructed such that the following problem is undecidable: For a coloring o
