✦ Synopsis


FHT is a homological finiteness condition of monoids that was introduced by Pride and Wang. For finitely presented groups this property is equivalent to the homological finiteness condition FP 3 , but for finitely presented monoids in general it is strictly stronger than the conditions left-FP 3 and right-FP 3 together. Here we define the notion of bi-FP n for monoids, using bimodules instead of left-or right-modules, and by establishing an exact sequence involving the relation bimodule of a monoid, we prove that for finitely presented monoids the property FHT is equivalent to the finiteness condition bi-FP 3 .
