We have recently proved that the generators of the second quantized centerless Virasoro (or Witt)-Zamolodchikov-w(infinity) algebra can be expressed in terms of the Renormalized Higher Powers of White Noise (RHPWN) and conjectured that this inclusion might in fact be an identity, in the sense that the converse is also true. In this paper we prove that this conjecture is true. We also explain the difference between this result and the boson representation of the centerless Virasoro algebra, which realizes, in the 1-mode case (in particular without renormalization), an inclusion of this algebra into the full oscillator algebra. This inclusion was known in the physics literature and some heuristic results were obtained in the direction of the extension of this inclusion to the 1-mode centerless Virasoro (or Witt)-Zamolodchikov-w(infinity) algebra. However, the possibility of an identification of the second quantizations of these two algebras was not even conjectured in the physics literature.

Abstract

We have recently proved that the generators of the second quantized centerless Virasoro (or Witt)-Zamolodchikov-w(infinity) algebra can be expressed in terms of the Renormalized Higher Powers of White Noise (RHPWN) and conjectured that this inclusion might in fact be an identity, in the sense that the converse is also true. In this paper we prove that this conjecture is true. We also explain the difference between this result and the boson representation of the centerless Virasoro algebra, which realizes, in the 1-mode case (in particular without renormalization), an inclusion of this algebra into the full oscillator algebra. This inclusion was known in the physics literature and some heuristic results were obtained in the direction of the extension of this inclusion to the 1-mode centerless Virasoro (or Witt)-Zamolodchikov-w(infinity) algebra. However, the possibility of an identification of the second quantizations of these two algebras was not even conjectured in the physics literature.
