John Morgan, Gang Tian's Ricci Flow and the Poincare Conjecture PDF

By John Morgan, Gang Tian

ISBN-10: 0821843281

ISBN-13: 9780821843284

For over a hundred years the Poincaré Conjecture, which proposes a topological characterization of the 3-sphere, has been the crucial query in topology. due to the fact that its formula, it's been time and again attacked, with out luck, utilizing quite a few topological equipment. Its value and hassle have been highlighted whilst it was once selected as one of many Clay arithmetic Institute's seven Millennium Prize difficulties. In 2002 and 2003 Grigory Perelman published 3 preprints displaying tips to use geometric arguments, particularly the Ricci circulation as brought and studied by means of Hamilton, to set up the Poincaré Conjecture within the affirmative. This ebook presents complete info of a whole evidence of the Poincaré Conjecture following Perelman's 3 preprints. After a long advent that outlines the total argument, the ebook is split into 4 components. the 1st half reports worthwhile effects from Riemannian geometry and Ricci movement, together with a lot of Hamilton's paintings. the second one half begins with Perelman's size functionality, that is used to set up an important non-collapsing theorems. Then it discusses the category of non-collapsed, historic ideas to the Ricci movement equation. The 3rd half matters the life of Ricci movement with surgical procedure for all optimistic time and an research of the topological and geometric alterations brought through surgical procedure. The final half follows Perelman's 3rd preprint to turn out that after the preliminary Riemannian 3-manifold has finite basic team, Ricci circulate with surgical procedure turns into extinct after finite time. The proofs of the Poincaré Conjecture and the heavily comparable three-dimensional round space-form conjecture are then speedy. The lifestyles of Ricci move with surgical procedure has software to 3-manifolds a long way past the Poincaré Conjecture. It kinds the center of the facts through Ricci circulate of Thurston's Geometrization Conjecture. Thurston's Geometrization Conjecture, which classifies all compact 3-manifolds, may be the topic of a follow-up article. The association of the fabric during this booklet differs from that given by means of Perelman. From the start the authors current all analytic and geometric arguments within the context of Ricci stream with surgical procedure. additionally, the fourth half is a much-expanded model of Perelman's 3rd preprint; it supplies the 1st whole and targeted facts of the finite-time extinction theorem. With the big quantity of history fabric that's awarded and the special types of the crucial arguments, this publication is acceptable for all mathematicians from complex graduate scholars to experts in geometry and topology. The Clay arithmetic Institute Monograph sequence publishes chosen expositions of contemporary advancements, either in rising parts and in older matters remodeled by way of new insights or unifying rules. Titles during this sequence are co-published with the Clay arithmetic Institute (Cambridge, MA).

The Hauptvermutung is the conjecture that any triangulations of a polyhedron are combinatorially identical. This conjecture used to be formulated on the flip of the century, and till its answer used to be a primary challenge of topology. at the start, it was once confirmed for low-dimensional polyhedra, and it could possibly were anticipated that additional improvement of high-dimensional topology may result in a verification in all dimensions. despite the fact that, in 1961 Milnor developed high-dimensional polyhedra with combinatorially inequivalent triangulations, disproving the Hauptvermutung usually. Then, the advance of surgical procedure concept ended in the disproof of the high-dimensional manifold Hauptvermutung within the overdue Nineteen Sixties. in past times, the printed list of the Hauptvermutung has been incomplete. This quantity brings jointly the unique papers of Casson and Sullivan (1967), and the `Princeton Notes at the Hauptvermutung' of Armstrong, Rourke and Cooke (1968/1972). They contain numerous effects that have turn into a part of mathematical folklore, yet of which proofs had by no means been released. the cloth is complemented via an advent at the Hauptvermutung and an account of modern advancements within the zone. additionally, references were up to date at any place attainable. viewers: This ebook can be beneficial to all mathematicians drawn to the topology of manifolds, geometry, and differential geometry.

ISBN-13: 9780198502692

The final ten years have noticeable quick advances within the knowing of differentiable four-manifolds, no longer least of which has been the invention of latest 'exotic' manifolds. those effects have had far-reaching results in geometry, topology, and mathematical physics, and feature confirmed to be a mainspring of present mathematical study. This e-book offers a lucid and obtainable account of the fashionable examine of the geometry of four-manifolds. accordingly, it is going to be required interpreting for all these mathematicians and theoretical physicists whose study touches in this subject. The authors current either an intensive therapy of the most strains of those advancements in four-manifold topology--notably the definition of latest invariants of four-manifolds--and additionally a wide-ranging remedy of suitable subject matters from geometry and worldwide research. the entire major theorems approximately Yang-Mills instantons on four-manifolds are confirmed intimately. at the geometric facet, the ebook incorporates a new evidence of the category of instantons at the four-sphere, including an in depth dialogue of the differential geometry of holomorphic vector bundles. on the finish of the publication the several strands of the speculation are introduced jointly within the proofs of effects which settle long-standing difficulties in four-manifolds topology and that are on the subject of the frontiers of present examine. Co-author Donaldson is the 1994 co-recipient of the celebrated Crafoord Prize.
