He also established the existence of the first-known abnormal minimizer in sub-Riemannian geometry, and is known for investigations using gauge-theoretic ideas of how a falling cat lands on its feet. He has written one book on sub-Riemannian geometry.<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'> <o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>The PIMS Marsden Memorial Lecture Series is dedicated to the memory of Jerrold E Marsden (1942-2010), a world-renowned Canadian applied mathematician. Marsden was the Carl F Braun Professor of Control and Dynamical Systems at Caltech, and prior to that he was at the University of California, Berkeley, for many years. He did extensive research in the areas of geometric mechanics, dynamical systems and control theory. He was one of the original founders in the early 1970s of reduction theory for mechanical systems with symmetry, which remains an active and much studied area of research today.<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>July 25, 2012<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>2:00 pm<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>Fields Institute<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>Room 230<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>----------------------------------------------------<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'> <o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>Clare Kiernan<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>Communications Manager<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'> <o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>Pacific Institute for the Mathematical Sciences<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D;mso-fareast-language:EN-CA'>Web: www.pims.math.ca | Twitter: @pimsmath<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p></div></body></html>
