Abstract

Following a result of D.~Bylik and M.T.~Lacey from 2008 it is known that there exists an absolute constant η>0\eta>0 such that the (unnormalized) LL^{\infty}-norm of the three-dimensional discrepancy function, i.e, the (unnormalized) star discrepancy DND^{\ast}_N, is bounded from below by DNc(logN)1+ηD_{N}^{\ast}\geq c (\log N)^{1+\eta}, for all NNN\in\mathbb{N} sufficiently large, where c>0c>0 is some constant independent of NN. This paper builds upon their methods to verify that the above result holds with η<1/(32+441)0.017357\eta<1/(32+4\sqrt{41})\approx 0.017357\ldots
