For all sufficiently large odd integers n, the following version of Higman's embedding theorem is proved in the variety B n of all groups satisfying the identity x n = 1 . A finitely generated group G from B n has a presentation G = 〈 A | R 〉 wit

We prove that for every r > 0 r>0 if a nonpositively curved ( p , q ) (p,q) -map M M contains no flat submaps of radius r r , then the area of M M does not exceed C r n Crn for some constant C C . This strengthens a theorem of Ivanov and Schupp. We s
