• SOME PROPERTIES OF LINEAR COMBINATIONS OF TWO IDEMPOTENT MATRICES OVER SKEW FIELD

WENHUI LAN*, JUNQING WANG

Abstract


In this paper, idempotent matrices over skew field have been researched and some properties of idempotent matrices were extended from general complex domain to skew field. In this paper, the following conclusions were obtained: (1) the four equivalent conditions of idempotent matrices over skew field;(2) the necessary and sufficient conditions which could infer that the linear combinations

Keywords
