rectifiable arcs and P(E2) -, 0; (d) E has a tangent at x for p.a.s. x in E. It is easy to give examples of sets E which are regular but not strongly regular, but if 0. The book is devoted to the related theory and practice of ends, dealing with manifolds and CW complexes in topology and chain complexes in algebra. The first part develops a homotopy model of the behaviour at infinity of a non-compact space.

Tangent measures have been used to great effect in relating local features of a measure to properties such as integral dimensionality and rectifiability. For example, the proof of Preiss’ theorem uses tangent measures to reduce density properties to more manageable questions on the structure of m-uniform measures, that is measures v with v(B.

In mathematics, a rectifiable set is a set that is smooth in a certain measure-theoretic sense. It is an extension of the idea of a rectifiable curve to higher dimensions; loosely speaking, a rectifiable set is a rigorous formulation of a piece-wise smooth set.

As such, it has many of the desirable properties of smooth manifolds, including tangent spaces that are defined almost everywhere.

The author provides a firm and unified Price: $ In measure theory, tangent measures are used to study the local behavior of Radon measures, in much the same way as tangent spaces are used to study the local behavior of differentiable t measures (introduced by David Preiss in his study of rectifiable sets) are a useful tool in geometric measure example, they are used in proving Marstrand’s theorem and Preiss' theorem.

Abstract. We introduce tangent measures in the sense of David Preiss. We discuss their applications to the density and rectifiability properties of general Borel measures in ℝ n as well as to the behaviour of certain singular integrals with respect to such by: 7.

The focus of this book is geometric properties of general sets and measures in Euclidean spaces. Applications of this theory include fractal-type objects, such as strange attractors for dynamical systems, and those fractals used as models in the sciences.

It covers lots of material, including Marstrand and Priess’ results (about which I would recommend De Lellis’ notes on Rectifiable Sets, Densities and Tangent Measures), fractals and connections to singular integrals.

It contains things that none of the other books I am commenting on have, and it is the only representative of the harmonic. Abstract A measure is 1-rectifiable if there is a countable union of finite length curves whose complement has zero measure.

We characterize 1-rectifiable Radon measures μ in n-dimensional Euclidean space for all n ≥ 2 in terms of positivity of the lower density and finiteness of a geometric square function, which loosely speaking, records in an L2 gauge the extent to which μ admits Cited by: Chapter in the book The Abel Prize H.
