A short description of the symposium: CentroidalVoronoi tessellations (CVTs) are Voronoi tessellations of a bounded geometric domain such that the generating points of the tessellations are also the centroids of the corresponding Voronoi regions with respect to a given density function. CVT is a fundamental notion that has a wide spectrum of applications in computational science and engineering that include art design, astronomy, clustering, geometric modeling, image and data analysis, resource optimization, quadrature design, sensor networks, and numerical solution of partial differential equations. In addition, CVTs have been widely used in the design of optimal vector quantizers in electrical engineering. The goal of this symposium is to bring together scientists including the young researchers to discuss and exchange ideas in the areas of centroidal Voronoi tessellations and its applications.
