Download Foliations in Cauchy-Riemann Geometry (Mathematical Surveys by Elisabetta Barletta PDF

By Elisabetta Barletta

The authors learn the connection among foliation concept and differential geometry and research on Cauchy-Riemann (CR) manifolds. the most items of analysis are transversally and tangentially CR foliations, Levi foliations of CR manifolds, ideas of the Yang-Mills equations, tangentially Monge-AmpГѓВ©re foliations, the transverse Beltrami equations, and CR orbifolds. the newness of the authors' process is composed within the total use of the tools of foliation conception and selection of particular purposes. Examples of such purposes are Rea's holomorphic extension of Levi foliations, Stanton's holomorphic degeneracy, Boas and Straube's nearly commuting vector fields procedure for the examine of world regularity of Neumann operators and Bergman projections in multi-dimensional advanced research in different advanced variables, in addition to numerous purposes to differential geometry. Many open difficulties proposed within the monograph may perhaps allure the mathematical group and bring about extra purposes of foliation concept in complicated research and geometry of Cauchy-Riemann manifolds.

Download A Course on Elation Quadrangles by Koen Thas PDF

By Koen Thas

The concept of elation generalized quadrangle is a traditional generalization to the idea of generalized quadrangles of the $64000 proposal of translation planes within the idea of projective planes. virtually any recognized category of finite generalized quadrangles could be made from an appropriate category of elation quadrangles.

In this booklet the writer considers a number of features of the speculation of elation generalized quadrangles. designated recognition is given to neighborhood Moufang stipulations at the foundational point, exploring for example a query of Knarr from the Nineteen Nineties in regards to the very inspiration of elation quadrangles. all of the recognized effects on Kantor’s leading strength conjecture for finite elation quadrangles are accumulated, a few of them released right here for the 1st time. The structural concept of elation quadrangles and their teams is seriously emphasised. different comparable subject matters, comparable to p-modular cohomology, Heisenberg teams and lifestyles difficulties for definite translation nets, are in brief touched.

The textual content starts off from scratch and is basically self-contained. many different proofs are given for identified theorems. Containing dozens of workouts at a number of degrees, from really easy to quite tough, this path will stimulate undergraduate and graduate scholars to go into the interesting and wealthy international of elation quadrangles. The extra comprehensive mathematician will specially locate the ultimate chapters hard.
