WebTraditionally considered as a problem of number theory, it plays important role in many other areas of mathematics, for more details see [20]. Hurwitz and Radon proved that a formula of size [r;N;N] exists if and only if r ˆ(N), and this is still the only case where the Hurwitz problem is solved. 2The paper of Hurwitz was published posthumously. WebHurwitz's theorem implies that multiplicative formulas for sums of squares can only occur in 1, 2, 4 and 8 dimensions, a result originally proved by Hurwitz in 1898. It is a special case of the Hurwitz problem, solved also in Radon (1922).
