On the largest prime divisor of $n! + 1$

Li Lai

For an integer $m > 1$ , we denote by $P (m)$ the largest prime divisor of $m$ . We prove that $lim sup_{n \to + \infty} P (n! + 1) / n ⩾ 1 + 9 lo g 2 > 7.238$ , which improves a r…

On the rigidity of stationary charged black holes: small perturbations of the non-extremal Kerr-Newman family

Li Lai, Jiong-Yue Li, Pin Yu

We prove a perturbative result concerning the uniqueness of Kerr-Newman family of black holes: given an asymptotically flat space-time with bifurcate horizons, if it agrees with a…

A note on the number of irrational odd zeta values

Li Lai, Pin Yu

It is proved that, for all odd integer $s ⩾ s_{0} (ε)$ , there are at least $(c_{0} - ε) \frac{s ^{1/2}}{( l o g s ) ^{1/2}}$ many irrational numbers am…
