Rigidity and polyhedral combinatorics December 3 to December 7, 2007 American Institute of Mathematics, Palo Alto, CA Organizers: Robert Connelly, Ezra Miller, and Igor Pak Description: This workshop, sponsored by AIM and the NSF, will be devoted to polyhedral objects in Euclidean spaces. Specifically, which metric or combinatorial properties must change or remain constant under certain classes of deformations, such as bending, folding, stretching, or flexing? Deadline: July 15, 2007 Details: http://aimath.org/ARCC/workshops/polyhedralcomb.html
