Download E-books Scissors Congruences, Group Homology and Characteristic Classes (Nankai Tracts in Mathematics, V. 1.) PDF

By Johan L. Dupont

Those lecture notes are in line with a sequence of lectures given on the Nankai Institute of arithmetic within the fall of 1998. they supply an outline of the paintings of the writer and the overdue Chih-Han Sah on a variety of points of Hilbert's 3rd challenge: Are Euclidean polyhedra with a similar quantity "scissors-congruent", ie. can they be subdivided into finitely many pairwise congruent items? The publication starts off from the classical resolution of this challenge by way of M. Dehn. yet generalization to better dimensions and different geometries fast ends up in an exceptional number of mathematical issues, reminiscent of homology of teams, algebraic K-theory, features sessions for flat bundles, and invariants for hyperbolic manifolds. a few of the fabric, quite within the chapters on projective configurations, is released the following for the 1st time.

Download E-books Visual Geometry and Topology PDF

Geometry and topology are strongly inspired by means of the visualization of perfect gadgets that experience sure targeted features. a transparent formula of a selected estate or a logically constant facts of a theorem frequently comes basically after the mathematician has effectively "seen" what's going on. those photos that are intended to function signposts resulting in mathematical realizing, usually additionally comprise a great thing about their personal. The critical goal of this ebook is to relate, in an obtainable and reasonably visible language, approximately a few classical and glossy achievements of geometry and topology in either intrinsic mathematical difficulties and purposes to mathematical physics. The ebook starts off from classical notions of topology and ends with outstanding new leads to Hamiltonian geometry. Fomenko lays distinct emphasis upon visible factors of the difficulties and effects and downplays the summary logical facets of calculations. as an instance, readers can in a short time penetrate into the new conception of topological descriptions of integrable Hamiltonian differential equations. The e-book comprises a variety of graphical sheets drawn by way of the writer, that are offered in detailed sections of "Visual material". those photos illustrate the mathematical principles and effects inside the publication. utilizing those images, the reader can comprehend many glossy mathematical principles and tools. even if "Visual Geometry and Topology" is ready arithmetic, Fomenko has written and illustrated this booklet in order that scholars and researchers from all of the traditional sciences and likewise artists and artwork scholars will locate anything of curiosity inside its pages.

Download E-books Riemann Surfaces and Algebraic Curves: A First Course in Hurwitz Theory (London Mathematical Society Student Texts) PDF

Hurwitz thought, the examine of analytic features between Riemann surfaces, is a classical box and energetic study quarter in algebraic geometry. The subject's interaction among algebra, geometry, topology and research is a gorgeous instance of the interconnectedness of arithmetic. This ebook introduces scholars to this more and more very important box, masking key issues corresponding to manifolds, monodromy representations and the Hurwitz capability. Designed for undergraduate learn, this classroom-tested textual content contains over a hundred workouts to supply motivation for the reader. additionally incorporated are brief essays by way of visitor writers on how they use Hurwitz idea of their paintings, which levels from string concept to non-Archimedean geometry. even if utilized in a direction or as a self-contained reference for graduate scholars, this booklet will supply a thrilling glimpse at arithmetic past the normal college sessions.

Download E-books Basic Topological Structures of Ordinary Differential Equations (Mathematics and Its Applications) PDF

By V.V. Filippov

The purpose of this e-book is an in depth examine of topological results with regards to continuity of the dependence of ideas on preliminary values and parameters. this enables us to strengthen cost effectively a thought which offers simply with equations having singularities and with equations with multivalued correct hand facets (differential inclusions). An specific description of corresponding topological constructions expands the idea in relation to equations with non-stop correct hand aspects additionally. actually, it is a new technological know-how the place traditional Differential Equations, normal Topology, Integration concept and sensible research meet. In what matters equations with discontinuities and differential inclu­ sions, we don't limit the glory to the Cauchy challenge, yet we exhibit tips to boost a sophisticated concept whose quantity is commensurable with the amount of the prevailing idea of standard Differential Equations. the extent of the account rises within the publication step-by-step from moment yr scholar to operating scientist.

By Benoit Mandelbrot

Just 23 years in the past Benoit Mandelbrot released his recognized photograph of the Mandelbrot set, yet that photograph has replaced our view of the mathematical and actual universe. during this textual content, Mandelbrot bargains 25 papers from the earlier 25 years, many on the topic of the recognized inkblot determine.

Foundations of basic Topology provides the price of cautious displays of proofs and exhibits the ability of abstraction. This publication offers a cautious remedy of basic topology. geared up into eleven chapters, this ebook starts off with an outline of the $64000 notions approximately cardinal and ordinal numbers. this article then offers the basics of normal topology in logical order processing from the main common case of a topological house to the restrictive case of a whole metric area. different chapters ponder a basic strategy for finishing a metric house that's acceptable to the rationals and current the adequate stipulations for metrizability. This booklet discusses in addition the examine of areas of real-valued non-stop services. the ultimate bankruptcy bargains with uniform continuity of features, which contains discovering a distance that satisfies yes necessities for all issues of the distance at the same time. This booklet is a precious source for college kids and learn staff.
