FOCUS A The Way I Remember It In the fall of '47 I began to work on a Ph.D. thesis. My supervisor had me start by studying a chapter in Zygmund's book, dealing with uniqueness theorems for trigonometric series. Analogous work had been done for various other systems of functions, but only in one variable, as far as I could find out. I decided to try this problem for series of spherical harmonics. In the one-variable setting, properties of convex functions played a key role. This meant that I needed to find a good analogue of convexity for functions defined on the surface of a sphere. After a few unsatisfactory attempts I was led to reinvent the notion of subharmonicity (without giving it a name). When I found that F, Riesz had proved all the basic properties of subharmonic functions 20 years earlier I felt that I was on the right track. My final results were very similar to the best that were known in the classical case. I presented this at an AMS meeting at Duke, in April '49. Soon after an abstract of this talk appeared in print, I received an envelope from Zurich, containing a paper published in 1919 by Plancherel, a mathematician who had proved the most fundamental theorem about Fourier transforms. The paper he sent me dealt with the same problem that I had worked on! Fortunately, his results were much weaker than mine, he had to make stronger assumptions, so that the desired conclusions were only proved for a much smaller class of series. (He had preceded Riesz while I had followed him.) Now here is the point of all this: Had I known of Plancherel's paper, I would probably have been discouraged from tackling this problem. If this famous man could only get such weak results, what am I doing here? Sometimes a little ignorance is a good thing. (W. Rudin) 4.
