Speaker: Prof. Peter J. Olver (University of Minnesota) http://www.math.umn.edu/~olver/ Time: Friday, March 23, 2--3PM Room: RC-4082, East Wing of the Red Centre Building (UNSW) Joint Colloquium web site: http://www.maths.usyd.edu.au/u/SemConf/JointColloquium/index.html ----------------------------------------------- Title: Moving Frames in Applications Abstract: in this talk, I will describe a new approach to the theory of moving frames. The method is completely algorithmic, and applies to very general Lie group actions and even infinite-dimensional pseudo-groups. It has led to a wide variety of new applications, ranging over differential equations, the calculus of variations, geometric flows, image processing, numerical methods, differential geometry, invariant theory, and elsewhere. The talk will survey the key ideas, and present some of the principal applications. ----------------------------------------------- Lunch with speaker: we meet at 12:30PM at the entrance to the East Wing of Red Centre Building. One choice of commuting from Sydney: meet at Carslaw 620 around 12NOON and we share taxi to UNSW. The round trip is covered by department colloquium fund.
