Download E-books Blow-up Theory for Elliptic PDEs in Riemannian Geometry (MN-45): (Mathematical Notes) PDF

By Olivier Druet

Elliptic equations of severe Sobolev progress were the objective of research for many years simply because they've got proved to be of significant significance in research, geometry, and physics. The equations studied listed below are of the well known Yamabe sort. They contain Schrödinger operators at the left hand facet and a severe nonlinearity at the correct hand side.

an important improvement within the learn of such equations happened within the Eighties. It used to be came upon that the series splits right into a resolution of the restrict equation--a finite sum of bubbles--and a leisure that converges strongly to 0 within the Sobolev area inclusive of sq. integrable features whose gradient can also be sq. integrable. This splitting is named the vital thought for blow-up. during this ebook, the authors advance the pointwise concept for blow-up. They introduce new principles and techniques that result in sharp pointwise estimates. those estimates have vital functions while facing sharp consistent difficulties (a case the place the power is minimum) and compactness effects (a case the place the power is arbitrarily large). The authors rigorously and punctiliously describe pointwise habit while the power is arbitrary.

meant to be as self-contained as attainable, this available ebook will curiosity graduate scholars and researchers in quite a number mathematical fields.

Because the occasions of Gauss, Riemann, and Poincaré, one of many crucial pursuits of the learn of manifolds has been to narrate neighborhood analytic homes of a manifold with its international topological homes. one of the excessive issues in this direction are the Gauss-Bonnet formulation, the de Rham complicated, and the Hodge theorem; those effects exhibit, particularly, that the important software in achieving the most objective of world research is the idea of differential varieties.

The publication by way of Morita is a entire creation to differential kinds. It starts with a short creation to the inspiration of differentiable manifolds after which develops uncomplicated homes of differential types in addition to primary effects relating them, corresponding to the de Rham and Frobenius theorems. the second one half the e-book is dedicated to extra complicated fabric, together with Laplacians and harmonic kinds on manifolds, the recommendations of vector bundles and fiber bundles, and the idea of attribute sessions. one of the much less conventional subject matters taken care of is a close description of the Chern-Weil thought.

The e-book can function a textbook for undergraduate scholars and for graduate scholars in geometry.

By Catherine Chevalley

In 1982, Claude Chevalley expressed 3 particular needs with admire to the e-book of his Works. First, he acknowledged very in actual fact that any such booklet may still comprise his non­ technical papers. His purposes for that have been two-fold. One cause was once his lifestyles­ lengthy dedication to epistemology and to politics, which made him strongly against the view another way at present held that arithmetic includes purely half a guy. As he wrote to G. C. Rota on November twenty ninth, 1982: "An very important variety of papers released through me should not of a mathematical nature. a few have epistemological positive aspects which would clarify their presence in an version of amassed papers of a mathematician, yet various of them are all in favour of theoretical politics ( . . . ) they replicate a side of myself the omission of which might, i feel, provide a incorrect proposal of my traces of thinking". nevertheless, Chevalley idea that the accrued Works of a mathematician must be learn not just by way of different mathematicians, but in addition via historians of technological know-how.

Download E-books Morse Theory and Floer Homology (Universitext) PDF

By Michèle Audin, Mihai Damian

This ebook is an creation to trendy equipment of symplectic topology. it's dedicated to explaining the answer of an enormous challenge originating from classical mechanics: the 'Arnold conjecture', which asserts that the variety of 1-periodic trajectories of a non-degenerate Hamiltonian approach is bounded less than by way of the size of the homology of the underlying manifold.

The first half is an intensive advent to Morse conception, a primary instrument of differential topology. It defines the Morse advanced and the Morse homology, and develops a few of their applications.

Morse homology additionally serves an easy version for Floer homology, that's lined within the moment half. Floer homology is an infinite-dimensional analogue of Morse homology. Its involvement has been the most important within the fresh achievements in symplectic geometry and particularly within the evidence of the Arnold conjecture. The construction blocks of Floer homology are extra problematic and indicate using extra subtle analytical tools, all of that are defined during this moment part.

The 3 appendices current a couple of necessities in differential geometry, algebraic topology and analysis.

The booklet originated in a graduate path given at Strasbourg collage, and features a huge diversity of figures and routines. Morse thought and Floer Homology should be really priceless for graduate and postgraduate students.

By Peter W. Michor

This publication treats the basics of differential geometry: manifolds, flows, Lie teams and their activities, invariant idea, differential kinds and de Rham cohomology, bundles and connections, Riemann manifolds, isometric activities, and symplectic and Poisson geometry. The structure of the fabric stresses naturality and functoriality from the start and is as coordinate-free as attainable. Coordinate formulation are consistently derived as additional details. a few beautiful strange elements of this booklet are as follows: preliminary submanifolds and the Frobenius theorem for distributions of nonconstant rank (the Stefan-Sussman thought) are mentioned. Lie teams and their activities are handled early on, together with the slice theorem and invariant thought. De Rham cohomology comprises that of compact Lie teams, resulting in the research of (nonabelian) extensions of Lie algebras and Lie teams. The Frolicher-Nijenhuis bracket for tangent package valued differential kinds is used to specific any type of curvature and moment Bianchi identification, even for fiber bundles (without constitution groups). Riemann geometry starts off with a cautious therapy of connections to geodesic buildings to sprays to connectors and again to connections, going through the second one and 3rd tangent bundles. The Jacobi circulate at the moment tangent package deal is a brand new element coming from this standpoint. Symplectic and Poisson geometry emphasizes crew activities, momentum mappings, and mark downs. This ebook provides the cautious reader operating wisdom in quite a lot of subject matters of contemporary coordinate-free differential geometry in no longer too many pages. A prerequisite for utilizing this ebook is an efficient wisdom of undergraduate research and linear algebra.
