Pointwise dimension and exponential mixing

WebOct 17, 2024 · 1. There are plenty of families of zero entropy systems which can be either mixing or non-mixing. What comes ot my mind first is primitive substitution systems. … WebThis section discusses fundamental concepts such as Hausdorff dimension, box dimension, and pointwise dimension. 2.1 Hausdorff Measure and sDimension Let W be a set in the separable space Rn, i.e., W ⊂ Rn. The definitions of Hausdorff measure and dimension of W require several preliminary concepts. • A metric d(x,y) is defined on Rn ...

WebJun 10, 2024 · A centered finite difference method is exploited to discretize the spatial variables and leads to a system of the ordinary differential equation, in which the resulting coefficient matrix is complex symmetric and possesses the block Toeplitz structure. WebA large body of work utilises exponential mixtures of distributions (EMDs) for fusion. These mixtures are found by taking the weighted geometric mean of their components followed by scaling to ensure integration to unity. They have been widely used for fusion of single object (probability) distributions [2]. A well-known algorithm that utilises ... phillip levy goulston https://nextgenimages.com

We study the Navier–Stokes equations in dimension 3 (NS3D) driven by a noise which is white in time. We establish that if the noise is at the same time sufficiently smooth and non-degenerate in space, then the weak solutions converge exponentially fast to equilibrium. We use a coupling method. The arguments used in …

WebNotice that trivially exponential mixing implies mixing. However it was not known if it implies any stronger ergodic properties. Our main result (see Theorem 1.1) shows that exponential mixing implies the strongest ergodic property: Bernoullicity. In particular, it has the following non-trivial corollary: Corollary 1.2.
