Two types of local scale invariance are found which act as dynamical space-time symmetries of certain non-local free field theories. Physical applications include uniaxial Lifshitz points and ageing in simple ferromagnets.Latex2e + IOP macros, 4pp, based on talks given at Group24 and TH2002, Paris, July 2002Statistical MechanicsMaterials ScienceHigh Energy Physics - TheoryMathematical Physicstext
