We consider sequences of operators Un:L1(X)→ M(X), where X is a space of homogeneous type. Under certain conditions on the operators Un we give a complete characterization of convergence (divergence) sets of functional sequences Un(f), where f∈ Lp(X), 1≤ p≤ ∞. The results are applied to characterize convergence sets of some specific operator sequences in classical analysis.
