A W-transform-based criterion for the existence of bounded extensions of E-operators
Let Γ( H) be the symmetric Fock space over a Hilbert space H and ε :H→Γ(H) the exponential mapping. By an E-operator we mean an operator defined on ε( H). For an E-operator A, the composition mapping Φ= A∘ ε is called its W-transform. In this paper, we obtain a criterion based on the W-transform fo...

Summary: | Let
Γ(
H) be the symmetric Fock space over a Hilbert space
H and
ε
:H→Γ(H)
the exponential mapping. By an
E-operator we mean an operator defined on
ε(
H). For an
E-operator
A, the composition mapping
Φ=
A∘
ε is called its
W-transform. In this paper, we obtain a criterion based on the
W-transform for checking whether or not an
E-operator becomes a bounded linear operator on the Fock space. |
