Abstract
Let p be a prime. We complete the classification of pointed Hopf algebras of dimension p 2 over an algebraically closed field k. When char k ≠ p, our result is the same as the well-known result for char k = 0. When char k = p, we obtain 14 types of pointed Hopf algebras of dimension p 2, including a unique noncommutative and noncocommutative type.
