Group Theory in Non-Linear Problems: Lectures Presented at the NATO Advanced Study Institute on Mathematical Physics, held in Istanbul, Turkey, August 7-18, 1972

This is the second volume of a series of books in various aspects of Mathematical Physics. Mathematical Physics has made great strides in recent years, and is rapidly becoming an important discipline in its own right. The fact that physical ideas can help create new mathematical theories, and rigorous mathematical theo­ rems can help to push the limits of physical theories and solve problems is generally acknowledged. We believe that continuous con­ tacts between mathematicians and physicis...
