Popis: We characterize surjective isometries of the total variation distance between various subsets of Borel probability measures. In the case when isometries are w ⁎ -continuous or in the case when their domain consists of measures which are absolutely continuous with respect to a fixed measure, such isometries are push-forwards, i.e., compositum of a measure with a bijection. When the domain consists of all Borel probability measures, their classification is more involved.
