The Ergodic Theory of Lattice Subgroups (AM-172) (Annals of by Alexander Gorodnik,Amos Nevo PDF

By Alexander Gorodnik,Amos Nevo

The effects tested during this e-book represent a brand new departure in ergodic idea and an important enlargement of its scope. conventional ergodic theorems eager about amenable teams, and trusted the lifestyles of an asymptotically invariant series within the crew, the ensuing maximal inequalities in response to protecting arguments, and the transference precept. the following, Alexander Gorodnik and Amos Nevo enhance a scientific common method of the facts of ergodic theorems for a wide classification of non-amenable in the neighborhood compact teams and their lattice subgroups. uncomplicated common stipulations at the spectral concept of the gang and the regularity of the averaging units are formulated, which suffice to assure convergence to the ergodic suggest. specifically, this technique supplies an entire strategy to the matter of building suggest and pointwise ergodic theorems for the ordinary averages on semisimple algebraic teams and on their discrete lattice subgroups. additionally, an particular quantitative expense of convergence to the ergodic suggest is validated in lots of cases.

The subject of this quantity lies on the intersection of a number of mathematical fields of basic significance. those contain ergodic thought and dynamics of non-amenable teams, harmonic research on semisimple algebraic teams and their homogeneous areas, quantitative non-Euclidean lattice element counting difficulties and their software to quantity idea, in addition to equidistribution and non-commutative Diophantine approximation. Many examples and functions are supplied within the textual content, demonstrating the usefulness of the consequences established.

Read e-book online Poisson Structures: 347 (Grundlehren der mathematischen PDF

By Camille Laurent-Gengoux,Anne Pichereau,Pol Vanhaecke

Poisson buildings look in a wide number of contexts, starting from string idea, classical/quantum mechanics and differential geometry to summary algebra, algebraic geometry and illustration thought. In almost all these contexts, it seems that the Poisson constitution isn't a theoretical artifact, yet a key aspect which, unsolicited, comes besides the matter that's investigated, and its gentle homes are decisive for the answer to the matter in approximately all instances. Poisson constructions is the 1st ebook that gives a entire creation to the idea, in addition to an outline of different facets of Poisson structures. The first half covers solid foundations, the important half contains an in depth exposition of different recognized kinds of Poisson buildings and of the (usually mathematical) contexts within which they seem, and the ultimate half is dedicated to the 2 major functions of Poisson constructions (integrable platforms and deformation quantization). The transparent constitution of the e-book makes it enough for readers who encounter Poisson constructions of their study or for graduate scholars or complex researchers who are drawn to an introduction to the numerous features and functions of Poisson structures.​
