Group theoretical methods in elementary particle physics

The NATO Advanced Study Institute’s summer school in Istanbul had group‐theoretical methods as its principal theme. It consisted, as all such summer schools do, of lectures, seminars, and private discussions. It provided an opportunity for all participants to become acquainted with each other’s work and ideas. This was probably its most useful function. There were 58 participants, from the United States, from Europe, and from Turkey and the Middle East. There was, perhaps, an overemphasis on lectures; these started, as a rule, at 9:15 a.m. and often lasted until 1:00 p.m., with a short coffee break. Many afternoons were devoted to formal seminars and some of these lasted several hours. Nevertheless, there was sufficient opportunity for individual discussion, during and after meals, in the evening hours, and on some of the afternoons. All the lectures were recorded in mimeographed notes, which were distributed with a minimum of delay. They may be published soon.
