Abstract: The talk is based on joint work with A. Mejía Castaño, S. Montgomery, M. Vega and C. Walton. Let p and q be distinct prime numbers. We study the Galois objects and cocycle deformations of the noncommutative, noncocommutative, semisimple Hopf algebras of odd dimension p^3 and of dimension pq^2. We obtain that the p+1 non-isomorphic self-dual semisimple Hopf algebras of dimension p^3 classified by Masuoka have no non-trivial cocycle deformations.
