8th Annual Thomas Wolff Memorial Lecture Andrei Okounkov The algebra and geometry of random surfaces There exist deep and perhaps surprising connections between certain random surface models of direct probabilistic interest and algebraic geometry. The random surface models in question are rather simple: these are the socalled stepped surfaces, also known as 3D Ising interfaces at zero temperature, and their close relatives. Various matrix models may be also viewed as more distant members of the same family. The connections between these models and algebraic geometry go both ways. On the one hand, enumerative problems related to algebraic curves may be answered in terms of partition functions of random surface models with specific boundary conditions. On the other hand, the analysis of random surfaces models, including such basic questions as the law of large numbers and the fluctuations around it is controlled by some different geometry, which is, in a sense, the "probabilistic mirror" to the original enumerative problem. I'll try to explain both directions of this correspondence in my lectures."
Andrei Okounkov received his doctorate at Moscow State University in
1995 under Alexander Kirillov and
Grigori Olshanski. He worked at the University of Chicago and the University of California at Berkeley before joining the faculty of Princeton University in 2002.

The Thomas Wolff lectures, sponsored by donations from his widow and his parents, memorialize Caltech’s great analyst who was tragically killed at age 46 in an automobile accident in July 2000. Wolff was a specialist in analysis, particularly harmonic analysis. Professor Wolff made numerous highly original contributions to the mathematical fields of Fourier analysis, partial differential equations, and complex analysis. A recurrent theme of his work was the application of finite combinatorial ideas to infinite, continuous problems. His early work on the Corona theorem, done as a Berkeley graduate student, stunned the mathematical community with its simplicity. Tom never wrote it up himself since several book writers asked for permission to include the proof in their books where it appeared not long after he discovered it. After producing a number of very significant papers between 1980 and 1995, he turned to the Kakeya problem and its significance in harmonic analysis, works whose impact is still being explored. Peter Jones, professor of mathematics at Yale, described Tom’s contributions as follows: “The hallmark of his approach to research was to select a problem where the present tools of harmonic analysis were wholly inadequate for the task. After a period of extreme concentration, he would come up with a new technique, usually of astonishing originality. With this new technique and his wellknown ability to handle great technical complications, the problem would be solved. After a few more problems in the area were resolved, the field would be changed forever. Tom would move on to an entirely new domain of research, and the rest of the analysis community would spend years trying to catch up. In the mathematical community, the common and rapid response to these breakthroughs was that they were seen not just as watershed events, but as lightning strikes that permanently altered the landscape.” Tom Wolff was noted for his analytic prowess, the depth of his insights, and the passion with which he nurtured the talents of young mathematicians. We miss him.
