The five hundred twenty-third meeting of the American Mathematical Society was held at the University of Chicago on Thursday, Friday and Saturday, April 12, 13 and 14.There were a total of 360 registrations, including 317 members of the Society.By decision of the Council of the Society, there was a Symposium on Calculus of variations and its applications.The Symposium was supported by contract with the cosponsoring organization, the Office of Ordnance Research.Sessions of the Symposium were held on Thursday and Friday morning and on Thursday afternoon.In the first session on Thursday morning, Professor Eric Reissner of the Massachusetts Institute of Technology spoke on Variational methods in linear theory of elasticity] Professor D. C. Drucker of Brown University on Variational principles in the mathematical theory of plasticity ; and Professor J. B. Keller, New York University, on Variational methods in wave propagation.The Chairman of the session was
