Abstract

We define the class of quasi invo-regular rings and prove that they curiously coincide with the so-called invo-regular rings, recently introduced and explored by the present author in Ann. Univ. Mariae CurieSklodowska – Sect. Math. (2018).

Keywords:

Unit-regular rings, invo-regular rings, quasi invo-regular rings.
