Далее рассматриваются C∗-алгебры C∗(ρ), порожденные сплетающими операторами степеней эндоморфизма ρ полугруппы M(P). Найдены генераторы этих алгебр для каждого из трех возможных типов эндоморфизмов.</p></abstract><trans-abstract xml:lang="en"><p>We study the endomorphisms of the inverse semigroupM(P) generated by the free product of cones and show that three types of endomorphisms are possible.
