Electromagnetic theory was under discussion at the Second Symposium on Applied Mathematics of the American Mathematical Society held at MIT on July 29–31. Papers were presented on the status of the new covariant formulation of quantum electrodynamics, reformulations of electromagnetic field theory along classical lines, the solutions of several types of boundary value problems related to the Maxwell field theory, methods of solving boundary value problems, orbit theory and its applications, the response of linear electrical networks, nonlinear electrical networks, the abstract formulation of problems in the communication of information, and on random noise.
