We obtain a compact Sobolev embedding for H-invariant functions in compact metric-measure spaces, where H is a subgroup of the measure preserving bije.

J. T. Tyson, Sobolev spaces on metric-measure spaces. An approach based on upper gradients, New Mathematical Monographs, 27, Cambridge University Press, 2015. In this article, the authors introduce the Newton-Morrey-Sobolev space on a metric measure space $\mathscrX,d,\mu$. The embedding of the Newton-Morrey-Sobolev space into the H\"older space is. To keep the presentation short we assume the reader is familiar with the concept of Sobolev functions on a metric measure space ,. J.T.

The transition from smooth spaces to singular spaces where calculus is possible parallels the classical development from smooth functions to functions with weak or generalized derivatives. Moreover, there is a new way of looking at the classical geometric theory of Sobolev. The material can be roughly divided into three different types: classical, standard but sometimes with a new twist, and recent. The author first studies basic covering theorems and their applications to analysis in metric measure spaces. This is followed by a discussion on Sobolev spaces emphasizing principles that are valid in larger contexts. Notice that, as before, there is no restriction on the dimension of the domain. The theory of Sobolev mappings into metric spaces has been studied extensively in [2, 14, 19, 21–23, 25, 32, 33].In particular, $\mathbbH^n$ valued Sobolev mappings have been explored in [5, 10, 11, 19, 29].One motivation for the study of Sobolev extensions stems from the problem of approximating Sobolev. The following version of Sobolev spaces on the metric space X will be considered in this paper; see [6,. Shanmugalingam, N., Tyson, J.: Sobolev Spaces on Metric Measure Spaces.
