The Adler-shiota-van Moerbeke Formula for the Bkp Hierarchy
نویسنده
چکیده
We study the BKP hierarchy and prove the existence of an Adler– Shiota–van Moerbeke formula. This formula relates the action of the BW1+∞–algebra on tau–functions to the action of the “additional symmetries” on wave functions.

Adler-Shiota-van Moerbeke formula
We give an alternative proof of the Adler-Shiota-van Moerbeke formula for the BKP hierarchy. The proof is based on a simple expression for the generator of additional symmetries and the Fay identity of the BKP hierarchy. PACS: 02.30.Ik Mathematics Subject Classification (2000): 35Q58, 37K10
متن کاملTHE W1+∞(gls)–SYMMETRIES OF THE S–COMPONENT KP HIERARCHY
Adler, Shiota and van Moerbeke obtained for the KP and Toda lattice hierarchies a formula which translates the action of the vertex operator on tau–functions to an action of a vertex operator of pseudo-differential operators on wave functions. This relates the additional symmetries of the KP and Toda lattice hierarchy to the W1+∞–, respectivelyW1+∞×W1+∞– algebra symmeties. In this paper we gene...
متن کاملAdditional Symmetries and String Equation of the Ckp Hierarchy
Since its introduction in 1980, the Kadomtsev-Petviashvili(KP) hierarchy [1, 2] is one of the most important research topics in the area of classical integrable systems. In particular, the study of its symmetries plays a central role in the development of this theory. In this context, additional symmetries, which correspond to a special kind of symmetries depending explicitly on the independent...
متن کاملQ-deformed KP hierarchy: Its additional symmetries and infinitesimal Bäcklund transformations
We study the additional symmetries associated with the q-deformed Kadomtsev-Petviashvili (q-KP) hierarchy. After identifying the resolvent operator as the generator of the additional symmetries, the q-KP hierarchy can be consistently reduced to the so-called q-deformed constrained KP (q-cKP) hierarchy. We then show that the additional symmetries acting on the wave function can be viewed as infi...
متن کاملMatrix Integrals and the Geometry of Spinors
Recently H Peng [11] showed that the symmetric matrix model and the statistics of the spectrum of symmetric matrix ensembles is governed by a strange reduction of the 2Toda lattice hierarchy [12]. Adler and van Moerbeke [4, 5] (see also [2]) show that this reduction leads to vectors of Pfaffian tau-functions. However these Pfaffian tau-functions do not satisfy the Toda lattice hierarchy, but ra...
