Products of Toeplitz operators on the Fock space
Products of Toeplitz operators on the Fock space
Let $f$ and $g$ be functions, not identically zero, in the Fock space $F^2_\alpha$ of $\mathbb {C}^n$. We show that the product $T_fT_{\overline g}$ of Toeplitz operators on $F^2_\alpha$ is bounded if and only if $f(z)=e^{q(z)}$ and $g(z)=ce^{-q(z)}$, where $c$ is a nonzero constant and $q$ is a linear polynomial.
