This  workshop is dedicated to the recent developments in the theory of Hopf algebras with an emphasis on its many connections and applications in other areas of mathematics  and theoretical physics, such as the theory of monoidal categories, enumerative geometry and Schubert calculus, equivariant cohomology, combinatorics and combinatorial identities, actions and coactions on algebras, conformal and topological field theory as well as renormalization theory.
