Abstract [en]

We give formulas which determine the effective dimensions of path semigroups over an uncountable field and of truncated path semigroups over a field which is uncountable or of characteristic zero.

Abstract [en]

Motivated by the apperance of multisemigroups in the study of additive 2-categories, we define and investigate the notion of a multisemigroup with multiplicities. This notion seems to be better siutable for applications in higher representation theory.
