Most textbooks on the theory of numbers contain some information on arithmetical functions, usually results which are classical. My purpose is to carry the reader beyond the point at which the textbooks ab

Ramanujan Sums,x, r) = e(nx′, r). The sum c(n,r) is called a .. For fixed r, and with n restricted to the positive integers, we obtain an arithmetical function c(·, r). Some authors devote this function by c., so that c.(n) = c(n, r)

Multiplicative Functions,is stated to the contrary, the same is true of n and other integer variables. However, on some occasions n and other integer variables will be allowed to have negative and zero values. On such occasions it will be stated explicitly that this is the case.

Ramanujan Sums,en over all × such that 1 ≤ x ≤ r and (x, r) = 1, but it could be over any reduced residue system (mod r). This is because, if x ≡ x′ (mod r) then e(nx, r) = e(nx′, r). The sum c(n,r) is called a .. For fixed r, and with n restricted to the positive integers, we obtain an arithmetical function c(·,

Counting Solutions of Congruences,y a . of a congruence, with modulus r, we mean a solution (mod r), i.e., an ordered s-tuple of integers (x.,…, x.) that satisfies the congruence, with two s-tuples (x.,…, x.) and . that satisfy the congruence counted as the same solution if and only if x. ≡ x.′. (mod r) for i = 1,…, s.

Painstaking

Dirichlet Series and Generating Functions,chlet series such that for all values of s, the series does not converge absolutely (see Exercise 5.1). If the Dirichlet series of f does converge absolutely for some values of s then for those values of s the series determines a function which, as we shall see, serves as a generating function of f.

迷住

Generalized Arithmetical Functions,n we have used in this book. In this chapter we shall introduce the reader to this general setting, look at various examples, and obtain some general results that can be applied in the special situations contained in the examples.
