Topological complexity of smooth random functions: École d'Eté de Probabilités de Saint-Flour XXXIX-2009

These notes, based on lectures delivered in Saint Flour, provide an easy introduction to the authors’ 2007 Springer monograph “Random Fields and Geometry.”While not as exhaustive as the full monograph, they are also less exhausting,while still covering the basic material, typically at a more intuitive and less technical level. They also cover some more recent material relating to random algebraic topology and statistical applications. The notes include an introduction to the general theory of Gaussian random fields, treating classical topics such as continuity and boundedness. This is followed by a quick review ofgeometry, both integral and Riemannian, with an emphasis on tube formulae, toprovide the reader with the material needed to understand and use the Gaussian kinematic formula, the main result of the notes. This is followed by chapters on topological inference and random algebraic topology, both of which provide applications of the main results. The 2007 monograph has been very well received, but does not make for easyreading. The current notes, while not as exhaustive, are much more readable. As such, they provide a comparatively easy entry into a difficult, but important, area of research This is the main contribution of these notes.. There are no real competitors to these notes, beyond our 2007 book. Recent reprintings of Adler's 'Geometry of Random Fields' (1980) by SIAM and Vanmarke's 'Random Fields: Analysis and Synthesis' (1983) are not competitors. Both are terribly out of date. INDICE: 1 Introduction. 2 Gaussian Processes. 3 Some Geometry and Some Topology. 4 The Gaussian Kinematic Formula. 5 On Applications: Topological Inference. 6 Algebraic Topology of Excursion Sets: A New Challenge
