In this paper we describe models of several fragments of linear logic with the exponential operator ! (called Of course) in categories of linear spaces. We model ! by the Fock space construction in Banach (or Hilbert) spaces, a notion originally introduced in the context of quantum field theory. Several variants of this construction are presented, and the representation of Fock space as a space of holomorphic functions is described. This also suggests that the “non-linear” functions we arrive at via! are not merely continuous, but analytic.
