[Banach] Abstract of a paper by Aicke Hinrichs and Jan Vybiral

This is an announcement for the paper "Johnson-Lindenstrauss lemma for circulant matrices" by Aicke Hinrichs and Jan Vybiral.

Abstract: We prove a variant of a Johnson-Lindenstrauss lemma for matrices with circulant structure. This approach allows to minimise the randomness used, is easy to implement and provides good running times. The price to be paid is the higher dimension of the target space $k=O(\varepsilon^{-2}\log^3n)$ instead of the classical bound $k=O(\varepsilon^{-2}\log n)$.
