minimal left ideals with respect to subsets of semigroups; kernels with respect to subsets of semigroups; partial groups
Summary:
In the paper, the following concept are defined: (i) a minimal left (right, two-sided) ideal with respect to a subset $B$ of a semigroup $S$, (ii) a kernel with respect to a subset $B$ of a semigroup $S$, and their basic properties are investigated.
