In July 2009 Germany hosted the fiftieth foreign Mathematical Olympiad (IMO). For the first actual time the variety of engaging nations handed a hundred, with 104 international locations from all continents. Celebrating the fiftieth anniversary of the IMO offers a terrific chance to seem again during the last 5 many years and to check its improvement to develop into a global occasion.

We record the main profitable contestants, the result of the 50 Olympiads and the 112 international locations that experience ever taken half. it really is notable to work out that some of the world’s prime examine mathematicians have been one of the so much winning IMO contributors of their early life. Six of them gave displays at a different get together: Bollobás, Gowers, Lovász, Smirnov, Tao and Yoccoz. This publication is geared toward scholars within the IMO age crew and all those that have curiosity during this around the world major pageant for high school students.

Allow $v$ be a gentle vector box at the aircraft, that may be a map from the aircraft to the unit circle. The authors research enough stipulations for the boundedness of the Hilbert remodel $\textrm{H}_{v, \epsilon }f(x) := \text{p. v. }\int_{-\epsilon}^{\epsilon} f(x-yv(x))\;\frac{dy}y$ the place $\epsilon$ is a definitely selected parameter, decided by means of the smoothness houses of the vector box.
