Unit and idempotent additive maps over countable linear transformations

Let V be a countably generated right vector space over a field F and a E End(V F ) be a shift operator. We show that there exist a unit u and an idempotent e in End(V F ) such that 1 - u, a - u are units in End(V F ) and 1 - e, a - e are

Unification Modulo Associativity and Idempotency Is NP-complete

We show that the unification problem for the theory of one associative and idempotent function symbol (AI-unification), i.e. solving word equations in free idempotent semigroups, is NP-complete....
