Abstract

Weyl consistency conditions have been used in unitary relativistic quantum field theory to impose constraints on the renormalization group flow of certain quantities. We classify the Weyl anomalies and their renormalization scheme ambiguities for generic non-relativistic theories in 2+1 dimensions with anisotropic scaling exponent z=2; the extension to other values of z are discussed as well. We give the consistency conditions among these anomalies. As an application we find several candidates for a C-theorem. We comment on possible candidates for a CC-theorem in higher dimensions.

38 pages, 1 figure, 7 tables; We took out the section on arbitrary dimension in version:2 !! In version:3 , a section (Sec: V) with NEW RESULTS on possible C-theorem candidates in arbitrary dimensions is added; v4:matched with journal version and updated section II
