Itô Prize
Content The prize honors the memory and celebrates the legacy of Professor Kiyosi Itô and his seminal contributions to probability theory. It is awarded every two years to the best paper in Stochastic Processes and their Applications published in a period of two years. DescriptionThe Itô prize is awarded by the Elsevier journal Stochastic Processes and their Applications to reward a paper recently published in the journal that we feel has significantly advanced the theory or applications of stochastic processes. The prize also has the purpose of honoring the vast and seminal contributions of Professor K. Itô to the subject. Professor Kiyosi Itô was born on September 7, 1915 in Mie, Japan. In 2003 when the prize was first awarded, he turned 88 years old. In Japan this is a significant birthday, known as one’s “rice birthday,” since the characters for 88 resemble the character for rice. It was thus a fitting time to acknowledge the immense gifts Professor Itô has given to mathematics and to probability theory in particular, by naming this prize in his honor. It is also appropriate to remind ourselves of the contributions Professor Itô has made to the field, and how significant they are. The prize consists of a monetary award of $USD 5000 and is awarded at the Bernoulli Society Conference on Stochastic Processes and Their Applications celebrated in odd years, where the winner presents the Itô Lecture. About Kiyosi ItôK. Itô was born in 1915, in the prefecture of Mie in Japan. His invention of stochastic calculus is by now a central element in Probability Theory. It took nearly twenty five years for this work, which had been elaborated between 1942 and 1950, to permeate the field until it became a standard topic taught in every course on advanced probability. In 1970, K. Itô published a second revolutionary paper, in which he developed the theory of excursions of a Markov process. This work immediately inspired new studies, for Brownian excursions in particular, allowing to revisit and extend the pioneering work of Paul Lévy on this topic. K. Itô is the co-author, with H.P. Mc Kean, of the book Diffusion Processes and their Sample paths (1965), which has been extremely influential in the study of diffusion processes, say between 1965 and 1980. One should also mention Itô's book on infinite-dimensional Markov processes, a topic of which he was particularly fond, as can be seen from the Foreword in Selected Papers (1987) in which he writes: After several years it became my habit to observe even finite-dimensional facts from the infinite-dimensional viewpoint. Indeed, this viewpoint is extremely fruitful, as Itô's theory of excursions shows very clearly. I consider that Malliavin Calculus hinges upon the same general principle (this is not a very original statement!) K. Itô has founded an extremely powerful probabilistic school in Japan; among his students let me mention N. Ikeda, H. Kunita, M. Fukushima and S. Watanabe, each of whom had also many students who continued to develop their master's field. To summarize, K. Itô is one of the greatest probabilists of the twentieth century, in the same vein as P. Lévy and A. Kolmogorov. (From Kiyosi I Itô remembered (1915-2008), by Marc Yor, Bernoulli News Vol. 16, No 1, May 2009, http://isi.cbs.nl/bnews/09a/index.html).
