SUMMARY:Talk: Generic Rigidity and the Grassmannian Abstract

DESCRIPTION:
 Join SUM at a talk given by one of Lawrence's 
 math professors, Alex Heaton! Prof. Heaton will 
 give a talk on generic rigidity and the Grassmannian.\n
 \n
 Abstract: We place the vertices of a graph into 
 space and treat the edges as rigid bars allowed 
 to rotate about joints at each vertex.  People 
 have studied the resulting objects for a long 
 time, going back to Maxwell, Cauchy, Mobius, and 
 others.  For example, Maxwell stated that a graph 
 must have at least 3|V| - 6 edges to have a chance 
 at being rigid in space.  In this talk I will 
 show how to decide if the graph is rigid or flexible 
 using combinatorial objects called Young Tableaux, 
 which appear frequently in representation theory 
 and geometry.\n\n
