....1998) and the forthcoming PhD thesis of one of the authors (Bruni 1998) 2. Double Categories and Generalized Natural Transformations A double category is an internal category in Cat. Due to the specific structure of Cat, double categories admit the following naive presentation, adapted from Kelly and Street (1974). Definition 1. Double Category) A double category D consists of a collection a; b; c; of objects (also called 0 cells) a collection h; g; f; of horizontal arrows (also called horizontal 1 cells) a collection v; u; w; of vertical arrows (also called vertical 1 cells) and a ....

.... Kampen Theorem for the fundamental crossed module, because they nicely handle subdivision and the homotopy addition lemma [9] They also have a monoidal closed structure, related to a notion of homotopy, and which may be derived from that for the case of all dimensions given in [14] 2 groupoids [45, 12] These are nearer to the well used 2 categories. On the other hand, their monoidal closed structure, which follows from the equivalence with the previous example, seems more difficult to describe than in either of the previous examples. The corresponding case of 2 categories is dealt with by Gray ....
