Our space X,d,µ is a metric measure space and hence one may deﬁne a Newtonian Sobolev space N 1,p X:= N 1,p X,d,µ based on upper gradients and.

Based on the fundamental concept of upper gradient, the notion of a Sobolev function was formulated in the setting of metric measure spaces supporting a Poincaré inequal. Metric measure spaces A metric measure space is defined to be a triple X, d, μ, where X, d is a separable metric space and μ is a nontrivial locally finite Borel-regular measure on X. Recall that locally finite means in this context see the text after 3.3.3 that for every point x ∈ X there is an r.

Jan 05, 2019 · Let X be a noncomplete metric measure space satisfying the usual local assumptions of a doubling property and a Poincaré inequality. We study extensions of Newtonian Sobolev functions to the completion X ˆ of X and use them to obtain several results on X itself, in particular concerning minimal weak upper gradients, Lebesgue points, quasicontinuity, regularity properties of the capacity.

Abstract. In this note, we give a new proof of Wolff potential estimates for Cheeger p-superharmonic functions on metric measure spaces given by Björn et al. J Anal Math 85:339–369, 2001.Also, we extend the estimate to Poisson type equations with signed data. Sobolev spaces on metric-measure spaces, denoted by M 1, p, have been introduced in, and they play an important role in the so called area of analysis on metric spaces,,. Later, many other definitions have been introduced in [6], [10], [11], [24], but in the important case when the underlying metric-measure space supports the Poincaré inequality, all the definitions are equivalent [8], [19].

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.

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.

While the approach based on upper gradients Cheeger and Newtonian Sobolev spaces requires the space to be highly connected, it does not apply to fractals with limited connectivity properties.

Oct 19, 2019 · In this paper, the authors present some new characterizations of the Musielak–Orlicz–Sobolev spaces with even smoothness order via ball averages and their derivatives on the radius. Consequently, as special examples of the Musielak–Orlicz–Sobolev spaces studied in this paper, the corresponding characterizations for some weighted Sobolev spaces, Orlicz–Sobolev spaces.

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.
