Full indefinite Stieltjes moment problem and Padé approximants

Full indefinite Stieltjes moment problem is studied via the step-by-step Schur algorithm. Naturally associated with indefinite Stieltjes moment problem are generalized Stieltjes continued fraction and a system of difference equations, which, in turn, lead to factorization of resolvent matrices of indefinite Stieltjes moment problem. A criterion for such a problem to be indeterminate in terms of continued fraction is found and a complete description of its solutions is given in the indeterminate case.
Explicit formulas for diagonal and sub-diagonal Pad´e approximants for formal power series corresponding to indefinite Stieltjes moment problem and convergence results for Pad´e approximants are presented.
