Abstract

Given a probability space (Ω,A,P), a Polish space X and a (B(X)A)-measurable function f:X × Ω→X we consider Borel and bounded solutions ψ:X→ℝ of the functional inequality

ψ(x) ≤ ∫Ωψ(f(x,ω))P(dω)

and a uniqueness-type problem for Borel and bounded solutions φ:X→ℝ of the functional equation

φ(x) = ∫Ωφ(f(x,ω))P(dω).
