On the renormalization procedure for quantum fields with modified dispersion relations in curved spacetimes

We review our recent results on the renormalization procedure for a free quantum scalar field with modified dispersion relations in curved spacetimes. For dispersion relations containing up to 2s powers of the spatial momentum, the subtraction necessary to renormalize 〈φ 2〉 and 〈T μν〉 depends on s....
