Abstract
Let e be an indecomposable idempotent of a serial ring R. A pp-type p(x) is called an e-type if e | x ∈ p; and pp-formula ϕ(x) is an e-formula if ϕ → e | x. For example, the pp-formula s | x for s ∈ Re is an e-formula. A e-pair is a pair 〈I, J〉, where I ⊂ eR is a right ideal and J ⊂ Re is a left ideal of R.
