Elisabeth Reitinger,B?rbel Traunsteiner Here we show that if the matrix entries are non-negative and an eigenvalue has geometric multiplicity at least two, then this eigenvalue lies in a smaller disk. The proof uses geometric rearrangement inequalities on sums of higher dimensional real vectors which is another new result of this paper.作者: 衣服 時間: 2025-3-22 12:21 作者: 精密 時間: 2025-3-22 14:24

Elisabeth Reitinger,B?rbel Traunsteiner’s Lemma” is best possible apart from an absolute constant factor. In other words, we show that no other argument can beat the Pigeonhole Principle proof of Siegel’s Lemma (apart from an absolute constant factor). To prove this, we combine a concentration inequality (i.e., Fourier analysis) with combinatorics.作者: STENT 時間: 2025-3-27 03:38 作者: botany 時間: 2025-3-27 08:32
