We study a class of holomorphic spaces Fp,m consisting of entire functions f on Cn such that ∂αf is in
the Fock space Fp for all multi-indices α with |α| m.We prove a useful Fourier characterization, namely,
f ∈ Fp,m if and only if zαf (z) is in Fp for all α with |α| = m. We obtain duality and interpolation results
for these spaces, including the interesting fact that, for 0
