DESCRIPTION:Tilmann Gneiting\, Heidelberg Institute for Theoretical Studi
 es (HITS) and Karlsruhe Institute of Technology (KIT)\nIn classical papers
 \, Iso Schoenberg (1938\, 1942) laid the ground for the study of isotropic
  positive definite functions on Euclidean spaces and spheres\, respectivel
 y. Subsequently\, positive definite functions on Euclidean spaces have bee
 n studied extensively in spatial statistics and related fields. In contras
 t\, positive definite functions on spheres have only recently moved into f
 ocus\, motivated by critical applied problems in the environmental and geo
 physical sciences that require correlation models on the surface of Planet
  Earth. I will review recent progress in the area\, with an eye on a listi
 ng of 18 open problems posed in 2013.\n\nPart of the Semester : Functiona
