Positive Toeplitz Operators Between Different Doubling Fock Spaces

Let $F^{p}(\phi)$ be the weighted Fock space on the complex plane $\mathbb{C}$, where $\phi$ is subharmonic with $\Delta \phi \, dA$ a doubling measure. In this paper, we characterize the positive Borel measure $\mu$ on $\mathbb{C}$ for which the induced Toeplitz operator $T_\mu$ is bounded (or compact) from one weighted Fock space $F^{p}(\phi)$ to another $F^{q}(\phi)$ for $0 \lt p, q \lt \infty$.
