The inversion of a matrix is, in general, a difficult problem involving calculations of several determinants and it is useful in practical applications to obtain parametric classes of matrices whose inverses could be obtained by simply changing the values of the parameters. The object of this paper is to consider such a class which is closely related to polynomial interpolation and to apply it to group representations.- On the Sum Σ (a-1, n), [(a, n) = 1]

By a quasi-field wo mean a set Q in which an addition and a multiplication are defined such that 1. Addition is an abelian group, 2. Multiplication is an abelian group, 3. The quasi-distributive law
a(b + c) + a = ab + ac
holds for all elements a, b, c ∈ Q.

For all functions f(x) bounded on the real axis and continuous in [ψ(0), ψ{a)], continuous on the right at ψ(a), and continuous on the left at ψ(0), the sequence {Ln(f; x)} converges uniformly f(ψ(x)) in [0, a].- On Vaidyanathaswamy's Class Division of the Residue Classes Modulo 'N'

Vaidyanathaswamy has shown that if the residue classes modulo N are separated into classes by putting all residues having the same greatest common divisor with N into one class, then the classes so obtained combine themselves by addition, that is to say, the aggregate formed by adding the residues of one class to those of another contain all the residues of any one class the same number of times.- On Gauss's Sums

For integral values of a, x, M let us define the function F (a, x, M) by the relation
F(a, x, M) = ∑m(mod M) exp2πi/m(am2 + xm),
where Σ indicates summation over a complete set of residues m(mod M) modulo M.

We shall adopt the following well-known notations for υ-functions:
q = eπiτ, Imτ > o ;
υ2 (x|τ) = Σ q(n+1/2)2(2n+2)xπi,
υ (x|τ) = Σ qn2 e2nxπi,
υ (x|τ) = Σ (-I)nqn2 e2nπi.
Here, as well as in the sequel, Σ denotes summation over all integers from -∞ to +∞.

The object of this note is to prove the following
THEOREM 1. Let p be an odd prime. Then
1p-1+2p-1+........+(p-1)p-1-p-(p-1)=0 (mod p2). (1)
1.1. The point in the above theorem is seen if we write the left side of (1) in the form
(1p-1-1)+(2p-1-1)+......+[(p-1)p-1-1]-[(p-1)+1]
which is=0 (mod p) by Fermat's and Wilson's theorems. The above theorem states that the left side of (1) is divisible by p2.
