A formula on Stirling numbers of the second kind and its application to the unstable $K$ -theory of stunted complex projective spaces

Osamu Nishimura

A formula on Stirling numbers of the second kind $S (n, k)$ is proved. As a corollary, for odd $n$ and even $k$ , it is shown that $k! S (n, k)$ is a positive multiple of the greatest…

Spectral and Timing Analysis of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR

Wataru B. Iwakiri, Katja Pottschmidt, Sebastian Falkner +13

We present an analysis of the spectral shape and pulse profile of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR during a spin-up state. The pulsar, which…
