Finite derivation type for large ideals
In this paper we give a partial answer to the following question: does a large subsemigroup of a semigroup S with the finite combinatorial property finite derivation type ( FDT ) also have the same property?

Zusammenfassung: | In this paper we give a partial answer to the following question: does a large subsemigroup of a semigroup
S
with the finite combinatorial property
finite derivation type
(
FDT
) also have the same property? A positive answer is given for large ideals. As a consequence of this statement we prove that, given a finitely presented Rees matrix semigroup
M

], the semigroup
S
has
FDT
if and only if so does
