Randomness is inherent to models of the physical, biological, and social world. Random topology models are important in a variety of complicated models including quantum gravity and black holes, filaments of dark matter in astronomy, spatial statistics, and morphological models of shapes, as well as models appearing in social media. The probabilistic method, theory of point processes, and ideas from stochastic and integral geometry have been central tools for proofs and efficient algorithms to measure topological quantities, such as Betti numbers of random geometric complexes.
The workshop topics include: random simplicial complexes, topological invariants in Gaussian random fields, and topological aspects of phase transitions, and geometry and topology of hard disks. A major theme of this workshop will center around computational issues and numerical experiments based on existing models and implementations.
This workshop focuses on building bridges - by developing a unified point of view and by emphasizing cross-fertilization of ideas and techniques from geometry, topology and combinatorics. New experimental evidence is crucial to this goal. The workshop emphasizes the computational and algorithmic aspects of the problems in topics including: Concentration of maps and isoperimetry of waists in discrete setting, configuration Space/Test Map scheme and theorems of Tverbeg type, Equipartitions of measures, social choice, van Kampen-Haefliger-Weber theory for maps of simplicial complexes, combinatorics of homotopy colimits, and discrete Morse theory.
The main purpose of the workshop is to review some recent progress on the existence of Engel structures and to stimulate further research by bringing into focus geometrically interesting questions and by making connections to the modern theory of four-manifolds. With this goal in mind, the workshop will bring together people with different areas of expertise: those responsible for previous work on Engel structures, experts in contact topology and related topics, and experts on four-manifolds. Questions of a more dynamical flavor as well as questions pertaining to subriemannian geometry may also be discussed.
