Abstract (EN):
We consider the symmetric inverse monoid I-n of an n-element chain and its inverse submonoids POIn, PODIn, POPIn and PORIn of all order-preserving, order-preserving or order-reversing, orientation-preserving and orientation-preserving or orientation-reversing transformations, respectively, and give descriptions of their Abelian kernels relative to decidable pseudovarieties of Abelian groups.
