The Ideal Structure of Semigroups of Linear Transformations with Upper Bounds on Their Nullity or Defect

Suppose V is a vector space with dim V = p ≥ q ≥ ℵ 0 , and let T(V) denote the semigroup (under composition) of all linear transformations of V. For α ∈ T (V), let ker α and ran α denote the "kernel" and the "range" of α, and write n(α) = dim ker α and d(α) = codim ran α. In this...

For α ∈ T (V), let ker α and ran α denote the "kernel" and the "range" of α, and write n(α) = dim ker α and d(α) = codim ran α. In this article, we study the semigroups AM(p, q) = {α ∈ T(V):n(α)
