On matrix invertible extensions over commutative rings
Grigore Calugareanu, Horia F. Pop, Adrian Vasiu
We introduce the class E2 (resp. SE2) of commutative rings R with the property that each unimodular 2 x 2 matrix with entries in R extends to an invertible 3 x 3 matrix (resp. inve…

On stable range one matrices
Grigore Calugareanu, Horia F. Pop
For 2 by 2 matrices over commutative rings, we prove a characterization theorem for left stable range 1 elements, we show that the stable range 1 property is left-right symmetric (…
