Description

A consistent formulation of lattice field theories in Robertson-Walker spaces is not possible in comoving coordinates. For renormalizable lattice theories, physical results do not agree with results obtained using dimensional regularization. Coordinate systems where such a formulation may be possible are described. Problems with quantization with these ''fixed-distance'' coordinate systems are discussed
