The Plane With Density r^p and The Poincaré Conjecture

Putting a density (as in calculus or physics) on the plane can make for some interesting geometry. Perelman used such an idea in his proof of the Poincaré conjecture. No prerequisites.   more››

Manifolds With Density

The idea of putting a density on a manifold has appeared throughout mathematics, recently in Perelman's paper on the Poincaré Conjecture. The prime example is Gauss space: R^n with Gaussian density. Despite interesting progress, the geometry of mani   more››

Scientific Event

  • 31-Oct-07

Random projections of regular polytopes and neighborliness

If an N-dimensional regular crosspolytope is projected to a uniform random d-dimensional subspace and N is large, then the projection has strong neighborliness properties, with high probability. Strong results in this direction were recently obtai   more››

Scientific Event

  • 26-Oct-07

Polytopes and arrangements: diameter and curvature

By analogy with the Hirsh conjecture, we conjecture that the order of the largest total curvature of the central path associated to a polytope is the number of inequalities defining the polytope. By analogy with a result of Dedieu, Malajovich and   more››

Scientific Event

  • 25-Oct-07

Klee-Minty cubes and the central path

We consider a family of LO problems over the n-dimensional Klee-Minty cube and show that the central path may visit all of its vertices in the same order as simplex methods do. This is achieved by carefully adding an exponential number of redundan   more››

Pivot v/s interior point methods: pros and cons

Linear Optimization (Programming) is probably the most successful and most intensively studied model in applied mathematics. First we give a survey of the governing algorithmic principles that lead to design Pivot and Interior Point Methods (IPMs)   more››

Pushing things around

Unsolved for over twenty-five years, a surprisingly difficult conjecture stated that a non-crossing polygonal chain of fixed-length edges in the plane can be continuously opened without crossing. Gunter Rote, Erik Demaine and I proved this Carpent   more››

Why things don't fall down - Art, geometry and engineering

Why do some geometric shapes hold together, while others are floppy and fall down? An eggshell and a convex dome are rigid, while polygons, with four or more sides of fixed length in the plane, flex. The geometric principles for convex shapes go b   more››

The geometry of rigid and non-rigid structures

Convex triangulated surfaces in three-space are rigid by Cauchy's Theorem. But what about non-convex surfaces? Some interesting recent examples of classes of non-convex surfaces have some convex-like properties, and yet are still rigid. On the oth   more››

Total Positivity and its Applications

A matrix is called totally positive (resp. totally nonnegative)if all of its minors are positive (resp. nonnegative). This important class of matrices grew out of three separate applications: Vibrating systems, interpolation, and statistics. Since   more››

Scaling, universality and spatio-temporal clustering in seismicity and rock fracture phenomena

In this talk, Dr. Davidsen will give an overview of new methods from nonlinear sciences and complex network theory to characterize temporal and spatio-temporal clustering of point processes with a particular focus on their application to seismicity a   more››
