Inequalities for square functions induced by operators on a Hilbert space
Author(s): Sakin Demir
Abstract: Let
U:
H→H be a unitary operatör on a Hilbert space
H and
for all

. Suppsoe that (n
k) is a lacunary sequence with no non-trivial common divisor, then there exists a positive constant
C such that
Let T be a contraction on a Hilbert space H and let
for all

. Suppose that (
nk) is a lacunary sequence with no non-trivial common divisor, then there exist a Hilbert space
K containing
H as a closed subspace, and an ortogonal projection
P:
K→H such that
