Mean curvature flow and isoperimetric inequalities

Geometric flows have many applications in physics and geometry. The mean curvature flow occurs in the description of the interface evolution in certain physical models. This is related to the property that such a flow is the gradientflow of the area functional and therefore appears naturally in problems wherea surface energy is minimized. The mean curvature flow also has many geometric applications, in analogy with the Ricci flow of metrics on abstract riemannian manifolds. One can use this flow as a tool to obtain classification resultsfor surfaces satisfying certain curvature conditions, as well as to constructminimal surfaces. Geometric flows, obtained from solutions of geometric parabolic equations, can be considered as an alternative tool to prove isoperimetric inequalities. On the other hand, isoperimetric inequalities can help in treating several aspects of convergence of these flows. Isoperimetric inequalitieshave many applications in other fields of geometry, like hyperbolic manifolds. Unique book which examines advances on isoperimetric problems related with geometric flows and suggests some new directions in the interplay between the two subjects. First book to give an introduction to the mean curvature flow with surgery starting with the basis of the existence of solutions and the careful exposition of the ideas in the analysis of singularities. The exposition is accessible to graduate students of mathematics with some basic knowledge of Riemannian geometry. INDICE: Foreword.- I.
