Web28 dec. 2011 · Abstract The standard model of cosmology is based on the existence of homogeneous surfaces as the background arena for structure formation. Homogeneity underpins both general relativistic and modified gravity models and is central to the way in which we interpret observations of the cosmic microwave background (CMB) and the … WebPositive homogeneity leads to consider more functions as homogeneous. For example, the absolute value and all norms are positively homogeneous functions that are not homogeneous. The restriction of the scaling factor to real positive values allows also considering homogeneous functions whose degree of homogeneity is any real number.
