Query: Structure of T- and S-matrices in unphysical sheets and resonances in
  three-body systems   Algorithm, based on explicit representations for the analytic continuation of
Faddeev components of the three-body T-matrix in unphysical energy sheets, is
employed to study mechanism of disappearance and formation of the Efimov levels
of the helium ^4He trimer.
