Inverse moment problem for non-Abelian Coxeter double Bruhat cells


We solve the inverse problem for non-Abelian Coxeter double Bruhat cells in terms of the matrix Weyl functions. This result can be used to establish complete integrability of the non-Abelian version of nonlinear Coxeter-Toda lattices in $GL_n$.

Key words: Non-Abelian lattices, Coxeter double Bruhat cells, inverse problems.
