RESUMO

We study the following questions that generalize the Restricted Burnside Problem. 1. Let n be a positive integer and w a group-word. Consider the class of all groups G satisfying the identity wn 1 and having the verbal subgroup w(G) locally finite. Is that a variety? 2. Let n be a positive integer and w a group-word. Suppose that G is a residually finite group in which any w-value has order dividing n. Is the verbal subgroup w(G) locally finite? In the case w = x the questions are precisely the Restricted Burnside Problem. According to Zelmanov this has positive solution. We show that the answer is positive for many other words w. The new results that we present are about multilinear commutators and Engel words. Our main tool is Zelmanovs techniques created in his solution of the Restricted Burnside Problem.
