The purpose of this paper is to consider finite generation and finite presentabil-Ž . ity of a Bruck᎐Reilly extension S s BR G, of a group G with respect to an endomorphism . It is proved that S is finitely generated if and only if G can be generated by a set of the form D ϱ A i , where A : G is fin
Let G, H be groups. G is called an extension of H if there is an epimorphism u: G + H . The congruence Ker u is uniquely determined by the normal subgroups N = o-l( la). Thus we may say that G is an extension of H by N . Analogously a monoid S is called an extension of a monoid C if there is an epi
