Abstract
Motivated by the possibility that it may be misleading to assume SU(3) symm etry in the analysis of hyperon P-decays, we study the sensitivity of the p olarized parton densities, derived from the world data on inclusive polariz ed deep inelastic lepton-nucleon scattering, to variation of the value of t he nonsinglet axial charge a, from its SU(3) value of 3F - D.
