Наслов предавања: PERMUTATION IDENTITIES

Апстракт: We give a general theory of binary permutation identities, considering them as morphisms in a sequence of categories whose objects are binary trees. For a given set of permutation identities, we describe the set of its consequences. We also consider the properties for a set of permutation identities to be mA-nice, and mAC-nice. We give an example of a set of permutation identities of the form u = v, v = w, that is 7AC-nice. This is a joint work with Aleksandar Krapež.
