Abstract
Let ϕ be an injective endomorphism of a ring A. We denote by Aℓ[[x, ϕ] the left skew (power) series ring consisting of formal series \( \sum\nolimits_{1 = 0}^\infty {a_i x^i }\) of the variable x with canonical coefficients ai ∈ A,where addition is defined naturally and multiplication is defined by the rule xi a = ϕ i(a)xi.
