We prove that the semigroup of matrix units is stable. Compact, countably compact and pseudocompact topologies \(\tau\) on the infinite semigroup of matrix units \(B_\lambda\) such that \((B_\lambda,\tau)\) is a semitopological (inverse) semigroup are described. We prove the following properties of...
