On a disjoint idempotent decomposition for linear combinations produced from n commutative tripotent matrices

Özdemir, Halim; Kişi, Emre; Uç, Mahmut (ELSEVIER SCIENCE INC, 2012)

It has been established a 3(n)-term disjoint idempotent decomposition ( DID) for the linear combinations produced from n (>= 2) commutative tripotent matrices, their products and their products of power 2 at most. The ...
On the quadraticity of linear combinations of quadratic matrices

Uç, Mahmut; Özdemir, Halim; A. Y. Ozban (TAYLOR & FRANCIS LTD, 2015)

are obtained. Our main results contain many of the results in the literature related to idempotency or involutivity of the linear combinations of idempotent and/or involutive matrices. Finally, some numerical examples are ...
