@article{Shchedrik_2015, title={Bezout Rings of Stable Range 1.5}, volume={67}, url={http://umj.imath.kiev.ua/index.php/umj/article/view/2027}, abstractNote={A ring $R$ has a stable range 1.5 if, for every triple of left relatively prime nonzero elements $a, b$ and $c$ in $R$, there exists $r$ such that the elements $a+br$ and $c$ are left relatively prime. Let $R$ be a commutative Bezout domain. We prove that the matrix ring $M_2 (R)$ has the stable range 1.5 if and only if the ring $R$ has the same stable range.}, number={6}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Shchedrik, V.
