Let A = i 0 A i be a standard graded Artinian K-algebra, where char K = 0. Then A has the Weak Lefschetz property if there is an element of degree 1 such that the multiplication × : A i → A i+1 has maximal rank, for every i, and A has the Strong Lefschetz property if × d : A i → A i+d has maximal ra
