Unbounded Weighted Composition Operators on Fock space

In this paper, we consider \emph{unbounded} weighted composition operators acting on Fock space, and investigate some important properties of these operators, such as $\text{calC}$-selfadjoint (with respect to weighted composition conjugations), Hermitian, normal, cohyponormal, and invertible. In addition, the paper shows that unbounded normal weighted composition operators are contained properly in the class of $\text{calC}$-selfadjoint operators with respect to weighted composition conjugations. The computation of the spectrum is carried out in detail.
