The Faddeev-Yakubovsky approach is applied to construct the Fredholm-type integral equations for these systems in framework of the Potential theory. The boundary-value problems are formulated for the Faddeev-Yakubovsky components of wave functions.8 pages, 30 kB, REVTEX; Talk given at the International Workshop "Meson--Barion interactions and Few--Body systems", Dubna, 28-30 April, 1994Nuclear TheoryFunctional Analysistext
