1. Introduction. Let (X, , m) be a σ-finite measure space and let T be a positive linear operator on L1 = L1(X, , m). T is called Markovian if

(1.1)

T is called sub-Markovian if

(1.2)

All sets and functions are assumed measurable; all relations and statements are assumed to hold modulo sets of measure zero.

For a sequence of L 1 + functions (ƒ 0, ƒ 1, ƒ 2, …), let

(ƒn ) is called a super additive sequence or process, and (sn ) a super additive sum relative to a positive linear operator T on L 1 if
