Abstract :We investigate new upper bounds for the Berezin radius and Berezin norm of $2\\times2$ operator matrices using the Cauchy-Buzano inequality, and we propose a required condition for the equality case in the triangle inequalities for the Berezin norms. We also show various Berezin radius inequalities for matrices with $2\\times2$ operators.
