Generating sets of finite singular transformation semigroups
... We denote the D-Green class of all singular self maps of defect r by Dn−r (1 ≤ r ≤ n − 1). It is clear that α ∈ Dn−1 if and only if there exist i, j ∈ Xn with i = j such that ker(α) is the equivalence relation on Xn generated by {(i, j )}, or equivalently, generated by {(j, i)}. In this case we def ...

Rational homotopy builds an equivalence of categories between simply connected spaces without torsion and algebraic categories which are easy to define and to work with (Therefore our problem tackled below is solved in rational homotopy theory, see for example [4]). Such a nice situation is out of re ...
