On tame semigroups generated by idempotents with partial null multiplication

Bondarenko, V.M.; Tertychna, O.M. (Algebra and Discrete Mathematics, 2008)

Let I be a finite set without 0 and J a subset in I×I without diagonal elements (i,i). We define S(I,J) to be the semigroup with generators ei, where i∈I∪0, and the following relations: e0=0; e2i=ei for any i∈I; eiej=0 ...
The Tits alternative for generalized triangle groups of type (3,4,2)

Howie, J.; Williams, G. (Algebra and Discrete Mathematics, 2008)

A generalized triangle group is a group that can be presented in the form G=⟨x,y |xp=yq=w(x,y)r=1⟩ where p,q,r≥2 and w(x,y) is a cyclically reduced word of length at least 2 in the free product Zp∗Zq=⟨x,y |xp=yq=1⟩. ...
