... (1) If F is any functor from C to the category of sets, the natural transformations between hX and F are in natural correspondence with the elements of F (X). (2) h is an equivalence of categories with a full subcategory of Hom(C ◦ , D). Proof. Given a natural transformation α : hX −→ F, we assign ...

... then r n = 1 (and hence r = 1), and nθ = 2πk, k = 0, ±1, ±2, .... Therefore θ = 2πk/n, where only the remainder of k modulo n is relevant. Thus the n roots are: 2πk 2πk z = cos + i sin , k = 0, 1, 2, ..., n − 1. n n For instance, if n = 3, the roots are 1 and ...

Fermat`s and Euler`s Theorem
... largest solution is x+dm0 = x+m, which does not belong to {0, 1, . . . , m−1}. So there are exactly d solutions for x. 10. See Examples 20.14 and 20.15, page 188. Homework for Section 20 (only the starred problems will be graded): ...
