In this paper, we estimate the stable ranks of a Banach algebra in terms of the stable ranks of its quotient algebra and ideal under the assumption that the quotient map splits. As an application, several results about the Bass and the connected stable ranks of nest algebras are obtained.
We investigate internal groupoids and pseudogroupoids in varieties of universal algebras, and we give a new description of internal groupoids in congruence modular varieties. We then prove that in any congruence modular variety an algebraically central extension is categorically central. The convers
