On integers of the forms k ± 2n and k2 n ± 1
... odd integers. On the other hand, Sierpiński [34] proved that there are infinitely many positive odd numbers k for which all k2n + 1 (n = 1, 2, . . .) are composite. In 1962, J.L. Selfridge (unpublished) discovered that for any positive integer n, the integer 78 557 · 2n + 1 is divisible by one of t ...

An Introduction to Contemporary Mathematics
... The goal is to introduce you to contemporary mainstream 20th and 21st century mathematics. This is not an easy task. Mathematics is like a giant scaffolding. You need to build the superstructure before you can ascend for the view. The calculus and algebra you will learn in college is an essential pa ...

... (since g0 has order n and χ0 gives an isomorphism of hg0 i with µn (C)), so that χ(G) = µn (C). Now we claim that H ∩ K = 1. Indeed, if h ∈ H ∩ K, then χ(h) = 1 since h ∈ K, but χ induces an isomorphism χ0 : H → µn (C), so χ(h) = χ0 (h) = 1 forces h = 1 since, in particular, χ0 is injective. We conc ...
