设f和g是C的Fock空间F2 α中的非恒零函数.证明了Toeplitz算子在F2 α上的乘积TfTg是有界的当且仅当f(z)= eq(z)和g(z)= ce−q(z),其中c是非零常数,q是线性多项式.
Let f and g be functions, not identically zero, in the Fock space F 2 α of C. We show that the product TfTg of Toeplitz operators on F 2 α 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.
