Download Finiteness Theorems for Limit Cycles by Yu. S. Ilyashenko PDF

By Yu. S. Ilyashenko

This e-book is dedicated to the subsequent finiteness theorem: A polynomial vector box at the genuine aircraft has a finite variety of restrict cycles. To end up the theory, it suffices to notice that restrict cycles can't collect on a polycycle of an analytic vector box. This strategy necessitates research of the monodromy transformation (also referred to as the Poincare go back mapping or the 1st go back mapping) akin to this cycle. to hold out this research, this publication makes use of 5 assets: the speculation of Dulac, use of the complicated area, answer of singularities, the geometric thought of standard types, and superexact asymptotic sequence. within the advent, the writer offers effects approximately this challenge that have been identified as much as the writing of the current publication, with complete proofs (except with regards to leads to the neighborhood idea and theorems on answer of singularities).

Download The best writing on mathematics 2010 by Mircea Pitici PDF

By Mircea Pitici

This anthology brings jointly the year's best writing on arithmetic from all over the world. that includes promising new voices along a number of the most well known names in arithmetic, The most sensible Writing on Mathematics makes on hand to a large viewers many articles no longer simply stumbled on anyplace else--and you do not need to be a mathematician to take pleasure in them. those writings supply incredible insights into the character, that means, and perform of arithmetic this day. They delve into the heritage, philosophy, instructing, and daily occurrences of math, and take readers backstage of modern preferred mathematical debates. the following readers will become aware of why Freeman Dyson thinks a few mathematicians are birds whereas others are frogs; why Keith Devlin believes there is extra to arithmetic than facts; what Nick Paumgarten has to assert in regards to the timing styles of recent York City's site visitors lighting (and why jaywalking is the main mathematically effective approach to go Sixty-sixth Street); what Samuel Arbesman can let us know in regards to the epidemiology of the undead in zombie flicks; and masses, a lot more.

as well as providing the year's so much memorable writing on arithmetic, this must-have anthology additionally incorporates a foreword by means of esteemed mathematician William Thurston and an informative creation by way of Mircea Pitici. This ebook belongs at the shelf of a person drawn to the place math has taken us--and the place it really is headed.

Download Geometric Analysis: Proceedings of an Ams Special Session by Ams Special Session on Geometric Analysis (1991 Temple PDF

By Ams Special Session on Geometric Analysis (1991 Temple University), Eric Grinberg

This quantity comprises the refereed court cases of the detailed consultation on Geometric research held on the AMS assembly in Philadelphia in October 1991. The time period "geometric research" is getting used with expanding frequency within the mathematical group, yet its that means isn't really solely fastened. The papers in this assortment may help to raised outline the concept of geometric research through illustrating rising tendencies within the topic. the themes lined diversity over a wide spectrum: crucial geometry, Radon transforms, geometric inequalities, microlocal research, harmonic research, research on Lie teams and symmetric areas, and extra. Containing articles various from the expository to the technical, this publication provides the newest ends up in a vast diversity of analytic and geometric issues

Download Quaternion orders, quadratic forms, and Shimura curves by Montserrat Alsina, Pilar Bayer PDF

By Montserrat Alsina, Pilar Bayer

Shimura curves are a far-reaching generalization of the classical modular curves. They lie on the crossroads of many parts, together with complicated research, hyperbolic geometry, algebraic geometry, algebra, and mathematics. This monograph offers Shimura curves from a theoretical and algorithmic point of view. the most themes are Shimura curves outlined over the rational quantity box, the development in their basic domain names, and the selection in their complicated multiplication issues. The examine of complicated multiplication issues in Shimura curves results in the learn of households of binary quadratic types with algebraic coefficients and to their class by way of mathematics Fuchsian teams. during this regard, the authors boost a conception filled with new chances that parallels Gauss' idea at the class of binary quadratic varieties with crucial coefficients by way of the motion of the modular staff. this can be one of many few on hand books explaining the idea of Shimura curves on the graduate pupil point. every one subject coated within the publication starts off with a theoretical dialogue by way of rigorously worked-out examples, getting ready the way in which for additional examine. Titles during this sequence are co-published with the Centre de Recherches Mathématiques.

By Victor Prasolov, Yulij Ilyashenko

This selection of articles from the self sustaining collage of Moscow is derived from the Globus seminars held there. they're given via international experts, from Russia and somewhere else, in quite a few components of arithmetic and are designed to introduce graduate scholars to a few of the main dynamic parts of mathematical examine. The seminars goal to be casual, wide-ranging and forward-looking, getting around the rules and ideas instead of formal proofs, and this consists of over to the articles right here. themes coated diversity from computational complexity, algebraic geometry, dynamics, via to quantity idea and quantum teams. the quantity as an entire is an interesting and intriguing assessment of up to date arithmetic.

By Dorothy Buck and Erica Flapan, Dorothy Buck, Erica Flapan

During the last 20-30 years, knot conception has rekindled its historical ties with biology, chemistry, and physics as a way of constructing extra subtle descriptions of the entanglements and homes of usual phenomena--from strings to natural compounds to DNA. This quantity is predicated at the 2008 AMS brief direction, functions of Knot thought. the purpose of the quick direction and this quantity, whereas now not protecting all features of utilized knot idea, is to supply the reader with a mathematical appetizer, so that it will stimulate the mathematical urge for food for additional learn of this fascinating box. No earlier wisdom of topology, biology, chemistry, or physics is thought. specifically, the 1st 3 chapters of this quantity introduce the reader to knot conception (by Colin Adams), topological chirality and molecular symmetry (by Erica Flapan), and DNA topology (by Dorothy Buck). the second one 1/2 this quantity is targeted on 3 specific functions of knot idea. Louis Kauffman discusses purposes of knot conception to physics, Nadrian Seeman discusses how topology is utilized in DNA nanotechnology, and Jonathan Simon discusses the statistical and vigorous homes of knots and their relation to molecular biology.
