Abstract

Leon Ehrenpreis was an outstanding world-class mathematician and a wonderful, warm person. I had a privilege to consider myself his friend for the last two decades. It is hard to do justice to his manifold mathematics and personality, but I will try to at least add some recollections to this tribute volume.

Notes

  1. 1.

    One can also read the AMS Notices article [30] for recollections of several Leon’s friends and colleagues. A volume on tomography [10] is also dedicated to Leon’s memory.

  2. 2.

    The Arcata meeting was also the place where I met for the first time other colleagues, whom I now consider as long-time friends (J. Boman, D. Finch, A. Markoe, E. T. Quinto, G. Uhlmann, and many others). I could not even imagine that twelve years later I would have a privilege to work at the same department at Texas A&M with another group of researchers whose work I studied and admired as a young mathematician in Russia, such as Ron Douglas, Ciprian Foias, Carl Pearcy, and Gilles Pisier.

  3. 3.

    For instance, when the so-called moment conditions [35, 42] for the standard Radon transform are written, checking their necessity boils down to noticing that the kth power (x⋅ω)k of the inner product of two vectors is a homogeneous polynomial of degree k with respect to each of them.
