Huang, Qinghe; Tang, Gaohua Quasipolar property of trivial Morita context. (English) Zbl 1291.16022 Int. J. Pure Appl. Math. 90, No. 4, 423-431 (2014). Summary: Let \(T:=\left(\begin{smallmatrix} R&M\\ N&S\end{smallmatrix}\right)\) be a trivial Morita context. This article concerns the quasipolar properties of trivial Morita contexts over local rings. Necessary and sufficient conditions for a single matrix of \(T\) (a trivial Morita context over local rings) to be quasipolar are obtained. And then we get a sufficient condition for \(T\) to be a quasipolar ring.
