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…

The normalized Laplacian spectra of the double corona based on $R$ -graph

Ping-Kang Yu, Gui-Xian Tian

For simple graphs $G$ , $G_{1}$ and $G_{2}$ , we denote their double corona based on $R$ -graph by $G^{(R)} \otimes {G_{1}, G_{2}}$ . This paper determines the normalized Laplacian spectrum o…
