摘要

The relativistic generalization of Faddeev-Yakubovsky approach is constructed in the form of the dispersion relations. The five-quark amplitudes for the low-lying pentaquarks including the u-, d-, s-quarks axe calculated. The poles of these amplitudes determine the masses and widths of theta-pentaquarks.
