چکیده
|
Let n and k be two positive integers, k ⩽ n and a be an n−square quaternion matrix. in this paper, some results on the k−numerical range of a are investigated. moreover, the notions of k-numerical radius, right k-spectral radius and k-norm of a are introduced, and some of their algebraic properties are studied.
