Adams type trace inequalities for multiple fractional integral operators in grand Lebesgue spaces with mixed norms are established. Operators under consideration contain multiple fractional integrals defined on the product of quasi-metric measure spaces, and one-sided multiple potentials. In the case when we deal with operators defined on bounded sets, the established conditions are simultaneously necessary and sufficient for appropriate trace inequalities. The derived results are new even for multiple Riesz potential operators defined on the product of Euclidean spaces.enMultiple fractional integral operatorsMixed norm grand Lebesgue spacesPotentials on quasi-metric measure spacesOne-sided potentialsBoundednessTrace inequalityjournal-articlehttps://doi.org/10.1515/fca-2020-0072
