Coordinate and point transformations are studied in the context of conformal symmetry. When invariance requirements on arbitrary rank tensors are involved in both contexts, the similitudes and differences in transformation laws and invariance conditions are analysed in connection with those on tenso
Present paper is a continuation of a discussion given by R. Coquereaux and A. Grossmann (Ann. PhJx N. Y. 143 (1982), 296) on analytic solutions of spatially closed Friedman universes with cosmological constant and radiation pressure. Our purpose is to find such solutions in the case of opened univer
In this paper, we derive a method to determine a conformal transformation in n-dimensional Euclidean space in closed form given exact correspondences between data. We show that a minimal data set needed for correspondence is a localized vector frame and an additional point. In order to determine th
