Adel N. Alahmadi, S. K. Jain, André Leroy · Bulletin of Mathematical Sciences · 2020
In this paper, the notions of invariance and parallel sums as defined by Anderson and Duffin for matrices [Series and parallel addition of matrices, J. Math. Anal. Appl. 26 (1969) 576–594] are generalized to von Neumann regular rings.
