The n-component KP hierarchy and representation theory

Abstract: It is the aim of the present article to give all formulations of the n-component KP hierarchy and clarify connections between them. The generalization to the n-component KP hierarchy is important because it contains many of the most popular systems of soliton equations, like the Davey–Stewartson system (for n=2), the two-dimensional Toda lattice (for n=2), the n-wave system (for n⩾3) and the Darboux–Egoroff system. It also allows us to construct natural generalizations to the Davey–Stewartson and Toda lattice … Show more

“…Then, we will get a soliton solution, which may be regarded as a solitary wave propagating on, e.g., a nuclear surface rather than a colliding soliton. [32][33][34] As Kac and van der Leur pointed out, 34 the dromion solution of the DSE was first studied from the point of view of the spinor formalism by Hernandez Heredero et al 35 Thus, we meet with an interesting and exciting problem of investigating an interrelation between the above approach to solutions of the DSE and NLSE ͑NLS hierarchy͒ and the present method for solving a -dependent HF equation on m ͑x , ĝ ͒ KPn . 30 The soliton solution was obtained by the so-called inverse spectral method.…”

“…Алгебра W N может быть определена через инвариантные полиномы Казимира из токов, коммутирующих с экранирующими зарядами Q αβ = J αβ (z) (достаточно потребовать коммутативности лишь с теми из них, которые отвечают простым положительным корням). Тогда генераторы алгебры превращаются просто в симметрические полиномы от диагональных картановских токов J α = J αα (z) ∈ h: 19) где сдвиги степеней координаты z возникают естественным образом, например, из формул бозонизации (3.10). Для этих полей вместо (3.9) имеем…”

“…Generalizations of KP hierarchy attract a lot of interests from both physical and mathematical points of view [1][2][3][4][5][6][7][8][9][10]. One kind of generalization is the so-called multi-component KP equation with self-consistent sources, which was initiated by V.K.…”
