by W.S.HATCHER and A.SHAFAAT in Quebec (Canada)’) Classically an identity is a statement of the form (1) Vxl , . . . , xn(p = q) where p and q are polynomials in the variables x1 , . . . , 2,. In [ 13 this notion is generalized to arbitrary categories in the following way: First we observe than an identity (1) can bt. considered as an ordered pair (p, q), p… (More)
