Query: Nonperturbative solution of scalar Yukawa model in two- and three-body
  Fock space truncations   The Light-Front Tamm-Dancoff method of finding the nonperturbative solutions
in field theory is based on the Fock decomposition of the state vector,
complemented with the sector-dependent nonperturbative renormalization scheme.
We show in detail how to implement the renormalization procedure and to solve
the simplest nontrivial example of the scalar Yukawa model in the two- and
three-body Fock space truncations incorporating scalar "nucleon" and one or two
scalar "pions".
