Lipschitz characterization of Fock spaces via the Fock distance
Lipschitz characterization of Fock spaces via the Fock distance
Let be the Fock space on , let be Lebesgue space, and let be the distance function associated with the Fock space parameter . Suppose , , and is an entire function on . Fock-space Lipschitz conjecture. The function belongs to if and only if there exists a non-negative continuous function such that
for all . This would provide a Lipschitz-type characterization of Fock spaces analogous to the known characterization of Bergman spaces; the paper notes that the relevant distance estimates are not yet sufficiently understood.
