A Fischer-Type Determinantal Inequality for Certain Accretive- Dissipative Matrices

We consider C-valued n×n matrices A such that both A and A2 are accretivedissipative. In this short note, we investigate determinantal Fischer-type inequalities for such matrices A and improve known approximations for detA. KCI Citation Count: 0
