It is shown that non-commutative coordinates which are transformed by quantum groups are the natural generalization of the notion of a tensor operator for usual groups and that the quantum group coactions induce semigroups of transformations of states of a system. Two examples of non-commutative transformations and the corresponding semigroups are considered.17 pages, LaTeX; one reference and the corresponding remark in the text have been addedHigh Energy Physics - TheoryQuantum AlgebraPhysical Meaning of Quantum Space-Time Symmetriestext
