Abstract: Liquid crystals are fluids carrying an orientational degree of freedom. Their rotational symmetries can be used to reduce their Lagrangian description. This talk shows how Euler-Poincaré reduction produces a unifying framework for liquid crystal dynamics. As a result, two major liquid crystal theories turn out to be equivalent. Moreover, these theories can be extended to deal with orientational defects, aka disclinations.
