摘要
In this paper, we aim to introduce new inequalities of the m-tuples of semi-Hilbert space operators. These inequalities, which are based on some numerical radius inequalities due to Dragomir et al. for a single operator on a Hilbert space. Further, we give a new formula of the A-Euclidean operator semi-norm of m-tuples of operators on a semi-Hilbert space.
