Wronskian solutions of the T-, Q- and Y-systems related to infinite dimensional unitarizable modules of the general linear superalgebra gl(M|N)

In [1] (Z. Tsuboi, Nucl. Phys. B 826 (2010) 399, arXiv:0906.2039), we proposed Wronskian-like solutions of the T-system for [M, NI-hook of the general linear superalgebra gl(M vertical bar N). We have generalized these Wronskian-like solutions to the ones for the general T-hook, which is a union of [M-1, N-1]-hook and [M-2, N-2]-hook (M = M-1 + M-2, N = N-1 + N-2). These solutions are related to Weyl-type supercharacter formulas of infinite dimensional unitarizable modules of gl(M vertical bar N). Our solutions also include a Wronskian-like solution discussed in [2] (N. Gromov, V. Kazakov, S. Leurent, Z. Tsuboi, JHEP 1101 (2011) 155, arXiv:1010.2720) in relation to the AdS(5)/CFT4 spectral problem. (C) 2013 Elsevier B.V. All rights reserved.
