Pages : 272

Book Description
Although research in curve shortening flow has been very active for nearly 20 years, the results of those efforts have remained scattered throughout the literature. For the first time, The Curve Shortening Problem collects and illuminates those results in a comprehensive, rigorous, and self-contained account of the fundamental results. The authors present a complete treatment of the Gage-Hamilton theorem, a clear, detailed exposition of Grayson's convexity theorem, a systematic discussion of invariant solutions, applications to the existence of simple closed geodesics on a surface, and a new, almost convexity theorem for the generalized curve shortening problem. Many questions regarding curve shortening remain outstanding. With its careful exposition and complete guide to the literature, The Curve Shortening Problem provides not only an outstanding starting point for graduate students and new investigations, but a superb reference that presents intriguing new results for those already active in the field.

Nonlinear Diffusion Equations and Their Equilibrium States, 3 PDF Author: N.G Lloyd
Publisher: Springer Science & Business Media
ISBN: 1461203937
Category : Mathematics
Languages : en
Pages : 567

Book Description
Nonlinear diffusion equations have held a prominent place in the theory of partial differential equations, both for the challenging and deep math ematical questions posed by such equations and the important role they play in many areas of science and technology. Examples of current inter est are biological and chemical pattern formation, semiconductor design, environmental problems such as solute transport in groundwater flow, phase transitions and combustion theory. Central to the theory is the equation Ut = ~cp(U) + f(u). Here ~ denotes the n-dimensional Laplacian, cp and f are given functions and the solution is defined on some domain n x [0, T] in space-time. FUn damental questions concern the existence, uniqueness and regularity of so lutions, the existence of interfaces or free boundaries, the question as to whether or not the solution can be continued for all time, the asymptotic behavior, both in time and space, and the development of singularities, for instance when the solution ceases to exist after finite time, either through extinction or through blow up.

Ahead of the Curve

Ahead of the Curve PDF Author: Jenny Rushmore
Publisher: Hardie Grant Publishing
ISBN: 1787138720
Category : Crafts & Hobbies
Languages : en
Pages : 464

Book Description
Ahead of the Curve is the first sewing book to empower curvy and plus size women to feel body confident by sewing a wardrobe that fits. Don’t change your body to fit your clothes – change your clothes to fit your body! Ahead of the Curve includes 5 basic garment patterns (UK sizes 16–36/US size 12–32/EUR sizes 44–64), which includes a pair of trousers, a t-shirt, a sleeveless top and two dress designs. Jenny takes you through a series of “Fit Clinics” – tutorials and case studies demystifying the fitting process – showing you how to adjust these patterns to master the perfect fit for your body shape. Once you have got to grips with this, you can go on to customize your closet and create an unlimited array of fantastic clothes that celebrate your body. If you’re curvy or plus size, trying to find clothes that fit and reflect your personal style can be incredibly difficult and frustrating. Plus size women feel constantly excluded and like they can’t express their personality through clothes. This book finally changes that.

Hamilton’s Ricci Flow

Hamilton’s Ricci Flow PDF Author: Bennett Chow
Publisher: American Mathematical Society, Science Press
ISBN: 1470473690
Category : Mathematics
Languages : en
Pages : 648

Book Description
Ricci flow is a powerful analytic method for studying the geometry and topology of manifolds. This book is an introduction to Ricci flow for graduate students and mathematicians interested in working in the subject. To this end, the first chapter is a review of the relevant basics of Riemannian geometry. For the benefit of the student, the text includes a number of exercises of varying difficulty. The book also provides brief introductions to some general methods of geometric analysis and other geometric flows. Comparisons are made between the Ricci flow and the linear heat equation, mean curvature flow, and other geometric evolution equations whenever possible. Several topics of Hamilton's program are covered, such as short time existence, Harnack inequalities, Ricci solitons, Perelman's no local collapsing theorem, singularity analysis, and ancient solutions. A major direction in Ricci flow, via Hamilton's and Perelman's works, is the use of Ricci flow as an approach to solving the Poincaré conjecture and Thurston's geometrization conjecture.

Equivalence, Invariants and Symmetry

Equivalence, Invariants and Symmetry PDF Author: Peter J. Olver
Publisher: Cambridge University Press

Optimal Transport

Optimal Transport PDF Author: Cédric Villani
Publisher: Springer Science & Business Media
ISBN: 3540710507
Category : Mathematics
Languages : en
Pages : 970

Book Description
At the close of the 1980s, the independent contributions of Yann Brenier, Mike Cullen and John Mather launched a revolution in the venerable field of optimal transport founded by G. Monge in the 18th century, which has made breathtaking forays into various other domains of mathematics ever since. The author presents a broad overview of this area, supplying complete and self-contained proofs of all the fundamental results of the theory of optimal transport at the appropriate level of generality. Thus, the book encompasses the broad spectrum ranging from basic theory to the most recent research results. PhD students or researchers can read the entire book without any prior knowledge of the field. A comprehensive bibliography with notes that extensively discuss the existing literature underlines the book’s value as a most welcome reference text on this subject.
