摘要

We address the issue of the relation between the canonical functional Schrodinger representation in quantum field theory and the approach of precanonical field quantization proposed by the author, which requires neither a distinguished time variable nor infinite-dimensional spaces of field configurations. We argue that the standard functional derivative Schrodinger equation can be derived from the precanonical Dirac-like covariant generalization of the Schrodinger equation under the formal limiting transition gamma(0)x -> delta(0), where the constant x naturally appears within precanonical quantization as the inverse of a small "elementary volume" of space. We obtain a formal explicit expression of the Schrodinger wave functional as a continuous product of the Dirac algebra valued precanonical wave functions, which are defined on the finite-dimensional covariant configuration space of the field variables and space-time variables.
