The KW theorem for the SKP hierarchy. (English) Zbl 0966.37033

Summary: The supersymmetric Kadomtsev-Petviashvili (SKP) hierarchy was first introduced by Yu. I. Manin and A. O. Radul [Commun. Math. Phys. 98, 65-77 (1985; Zbl 0607.35075)]. In this letter, by the factorization \(L^n=L_nL_{n-1}\cdots L_1\) with \(L_j=D+u_{j,0}+u_{j,-1}D^{-1}+u_{j,-2}D^{-2}+\cdots\), \(j=1,2\cdots n\), being the independent super-pseudodifferential operators, we construct the supersymmetric Miura transformation for the SKP hierarchy, which leads to decomposition of the second Poisson brackets based on \(L^n\) to a direct sum. Each term in the sum contains the second brackets for \(L_j\).
