In Memoriam

We are very saddened by the death of our colleague Professor William B. Arveson, on November 15, due to complications during surgery. Professor Arveson joined our department faculty in 1968. He had done his undergraduate studies at Cal Tech, and his graduate studies at UCLA. He soon came to be recognized as one of the world's leading research mathematicians studying algebras of operators on Hilbert spaces, and their applications, especially to quantum physics. Professor Arveson remained fully active in research up to the time of his death. Professor Arveson strongly inspired and influenced many other researchers. In particular, 29 doctoral students wrote their doctoral dissertations under his guidance.
