Spontaneous and Gravitational Baryogenesis
  Some problems of spontaneous and gravitational baryogenesis are discussed.
Gravity modification due to the curvature dependent term in gravitational
baryogensis scenario is considered. It is shown that the interaction of
baryonic fields with the curvature scalar leads to strong instability of the
gravitational equations of motion and as a result to noticeable distortion of
the standard cosmology.
