چكيده لاتين :
A bounded linear operator T on a Hilbert space H is concave, if for each x 2 H; kTxk2
2kTxk2 + kxk2 0. In this study, it is shown that if T is a concave operator then It is
injective. Also, observe that the only concave bilateral weighted shifts are
isometries. Finally we show that no concave weighted shift operators is hypercyclic.
