Abstract
Let be a hypersurface of degree in the complex projective space , , having only isolated singularities. Let be the associated Jacobian algebra and be a hyperplane in avoiding the singularities of , but such that is singular. We related the Lefschetz type properties of the linear maps induced by the multiplication by linear form to the singularities of the hyperplane section . Similar results are obtained for the Jacobian module .
