Abstract: We consider reheating after inflation in theories with a non-standard kineticterm. We show that the equation that exhibits parametric resonance is theHill-Whittaker equation, which is a particular case of the more general Hillequation. This equation is in general more unstable than the Mathieu equation,such that narrow resonance preheating may be efficient in theories with anon-canonical kinetic term.
