Title: Mathematical gems in Distance Geometry
Speaker: Professor Leo Liberti, CNRS LIX, Ecole Polytechnique
Abstract:
Distance geometry focuses on the concept of distance rather than points and lines. Its fundamental problem asks to draw a weighted graph in a given K-dimensional Euclidean space, so that each edge is drawn as a segment with length equal to the weight, and it has applications to many fields of science and engineering (e.g. protein folding, wireless networks, robotic control, nanostructures and more). Distance geometry results are scattered throughout the whole history of mathematics starting with the Greeks. I will present some of those I find most beautiful, from a selection including: Heron's theorem, Cauchy's theorem about rigidity of convex polyhedra, Goedel's theorem about realizability on a sphere, and Schoenberg's theorem linking Euclidean Distance Matrices and Positive Semidefinite Matrices.
Biography:
Leo Liberti obtained his Ph.D. in Global Optimization at Imperial College London, held postdoctoral fellowships at Politecnico di Milano and Ecole Polytechnique in France, where he then became professor and vice-president of his department. After two years as a Research Staff Member at IBM Research in New York, he became Research Director at CNRS and part-time professor at Ecole Polytechnique. His main research interests are mathematical programming with applications to industrial problems, optimization algorithms, and distance geometry.
