DESCRIPTION:Speaker: Josef Schicho\nhosted by Tamas Hausel\nAbstract: If we
  model the group of Euclidean displacements by the dual quaternions\, then
  we can represent motions in 3D-space by polynomials with dual quaternion 
 coefficients. Kinematic/geometric statements about the motions are reflect
 ed by algebraic statements in the algebra of these polynomials. In particu
 lar\, a variation of the fundamental theorem of algebra translates to a co
 nstruction of linkages tracing a prescribed curve.In the second part of th
 e talk\, we general the concepts introduced in the first part to nonration
 al curves and apply them to analyze paradoxically moving linkages\, i.e.\,
  linkages that should not move according to a parameter count of free vari
 ables and constraints.
