Reverse triangle inequality in Hilbert $C^{*}$ -modules

M. Khosravi, H. Mahyar, M. S. Moslehian

We prove several versions of reverse triangle inequality in Hilbert $C^{*}$ -modules. We show that if $e_{1}, ..., e_{m}$ are vectors in a Hilbert module $X$ over a $C^{*}$ -alge…

Bessel type inequalities in Hilbert C*-modules

S. S. Dragomir, M. Khosravi, M. S. Moslehian

Regarding the generalizations of the Bessel inequality in Hilbert spaces which are due to Bombiari and Boas--Bellman, we obtain a version of the Bessel inequality and some generali…
