Let
T be a bounded linear operator on a complex Hilbert space
H. In this paper we introduce a new class of operators:
k-quasi class
Q* operators. An operator
T is said to be
k-quasi class
Q* if it satisfies

for all
x∈
H, where
k is a natural number. We prove the basic properties of this class of operators.
