In this way, we distinguish new classes of transformation semigroups with meaningful relations, e.g., we show the class of all distal transformation semigroups <em class="a-plus-plus">⊂,</em> the class of all transformation semigroups decomposable into distal semigroups <em class="a-plus-plus">⊂,</em> and the class of all transformation semigroups (here, <em class="a-plus-plus">⊂</em&gt; is strict inclusion).}, number={11}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Hosseini, A. and Sabbaghan, M. and Shirazi, F.
