Abstract:

In the literature two notions of the word problem for a variety occur. A variety has a*decidable word problem*if every finitely presented algebra in the variety has a decidable word problem. It has a*uniformly decidable word problem*if there is an algorithm which given a finite presentation produces an algorithm for solving the word problem of the algebra so presented. A variety is given with finitely many axioms having a decidable, but not uniformly decidable, word problem. Other related examples are given as well. - published version (32p)
