چکیده
Vertex operators, which are disguised Darboux maps, transform solutions of the KP equation into new ones. In this paper, we show that the bi-infinite The final version appeared in: Comm. Math.

We compute an infinite system of differential equations that characterises the quasi-periodic solutions of the KP hierarchy ; that is, the solutions of this new hierarchy are precisely those solutions of the KP hierarchy coming from theta functions of Jacobians.

In this letter, we consider the second Hamiltonian structure of the constrained modified KP hierarchy. After mapping the Lax operator to a pure differential operator the second structure becomes the sum of the second and the third Gelfand-Dickey brackets defined by this differential operator. We simplify this Hamiltonian structure by factorizing the Lax operator into linear terms.

We investigate the Miura map between the dispersionless KP and dispersionless modified KP hierarchies. We show that the Miura map is canonical with respect to their bi-Hamiltonian structures. Moreover, inspired by the works of Takasaki and Takebe, the twistor construction of solution structure for the dispersionless modified KP hierarchy is given.

Abstract. To every partition n = n1 + n2 + · · · + ns one can associate a vertex operator realization of the Lie algebras a∞ and ĝln. Using this construction we make reductions of the s–component KP hierarchy, reductions which are related to these partitions. In this way we obtain matrix KdV type equations. Now assuming that (1) τ is a τ–function of the [n1, n2, . . . , ns]–th reduced KP hierar...
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...
