D. E. Littlewood showed that the quickest method of calculating the characters of the symmetric groups is by the use of the recurrence relations between the S-functions. He has given the tables of characters for the symmetric groups up to degree 10.- Canonical Basis for Ideals in a Polynomial Domain Over a Commutative Ring with Finite Basis for Ideals

Let A be a commutative ring with unit element and A[x] denote the ring of polynomials in x with coefficients from A. Hilbert's theorem is : -
If every ideal in A has a finite basis, then every ideal in A[x] also has a finite basis.
The proof of this as given by Van der Waerden in his Moderne Algebra Bd. II gives us no information beyond the fact that every ideal in A [x] has a finite basis. If we just reverse the argument in his proof we will be able to give actually a canonical basis for every ideal in A[x] which will be found to be a powerful tool in several applications.

The main object of the present paper is to show that the algebra of the Gaussian periods is identical with the algebra of the eth power residues mod p where p is a prime and e is a divisor of p-1. This algebra is obviously a particular case of the algebra of the eth power residues mod N where N is any integer. Since the system of residue classes mod N is abstractly identical with a cyclic group of order N, the above algebra may be interpreted to be the algebra of the eth power residues connected with a cyclic group of order N. It is therefore natural to enquire whether there is a similar algebra connected with any finite Abelian group. We shall however show by means of an example that this is not the case.- On the Significance and the Extension of the Chinese Remainder Theorem

A set of elements is said to form a group under a composition rule R or simply an R-group if
(i) for every two elements a and b of the set aRb is also an element of the set, i.e. the set is closed under R;
(ii) R is associative, i.e. for any three elements a,b,c, of the set (aRb)Rc=aR(bRc);
(iii) there exists an element e, called the identity element, such that for every element a of the set ake=eRa=a;
(iv) to every element a, there exists an element x=a-1 called the inverse of a, such that aRx=e. The group is called Abelian if R is commutative.

An arithmetic function f(N) is multiplicative if
f(MN)=f(M)f(N)
whenever the integers M, N are relatively prime. The function F(N) defined by the equation
F(N)=Σf1(δ)f2(N/δ)
summed for all divisors δ of N is called the composite of the two arithmetic functions f1, f2. If f1 and f2 are multiplicative, it is easy to see that their composite F (represented by f1, f2) is also multiplicative.
