Workshop Announcement: ---------------------------------------------------------------- Engel structures ---------------------------------------------------------------- April 17 to April 21, 2017 American Institute of Mathematics Research Conference Center San Jose, California http://aimath.org/workshops/upcoming/engelstr ------------ Description: ------------ This workshop, sponsored by AIM and the NSF, will be devoted to the emerging theory of Engel structures on four-manifolds, especially questions of rigidity versus flexibility, and its (potential) connections with contact topology, dynamics, and four-dimensional differential topology and gauge theory. The workshop is organized by Yakov Eliashberg, Dieter Kotschick, Emmy Murphy, and Thomas Vogel. For more details please see the workshop announcement page: http://aimath.org/workshops/upcoming/engelstr Space and funding is available for a few more participants. If you would like to participate, please apply by filling out the on-line form (available at the link above) no later than November 1, 2016. Applications are open to all, and we especially encourage women, underrepresented minorities, junior mathematicians, and researchers from primarily undergraduate institutions to apply. -------------------------------- AIM Research Conference Center: -------------------------------- The American Institute of Mathematics (AIM) hosts focused workshops in all areas of the mathematical sciences. AIM focused workshops are distinguished by their emphasis on a specific mathematical goal, such as making progress on a significant unsolved problem, understanding the proof of an important new result, or investigating the convergence between two distinct areas of mathematics.
