On Groups of Even Order

The Annals of Mathematics, 1955
odd order are soluble. We shall use the term involution for a group element of order 2. If m is the total number of involutions of 65 and if we set n = g/m, the same method shows that 65 contains a normal subgroup V distinct from 5 such that the index of V is either 2 or is less than [n(n + 2)/2]!

On the similarity of matrices of even order

Mathematical Notes, 2007
The author continues the study of the similarity of different classes of matrix pairs, which was begun in a previous paper [Math. Notes 73, No. 6, 871--888 (2003); translation from Mat. Zametki 73, No. 6, 923--941 (2003; Zbl 1058.15034)]. More precisely, this paper is devoted to the problem of similarity of pairs of matrices of even order with some ...

Even-Order Subharmonic Oscillations

Journal of Applied Physics, 1956
The generation of an even-order subharmonic, or harmonic, oscillation in a driven nonlinear resonant system described by just a cubic nonlinear term requires the simultaneous appearance of a zero-frequency component. This component effectively introduces a squared nonlinear term.

On the Determinants of Pan-Magic Squares of Even Order

The Mathematical Gazette, 1949
In Mathematical Note 1911, this journal, Vol. XXX, No. 290, A. H. MacColl forms the determinant Δ of a pan-magic square of order 4 and states that Δ = 0. He also remarks that “the property appears to be peculiar to pan-magic squares of order 4”.

An Even Order Search Problem

1987
How might simple real zeros of real valued continuous k-th derivatives g(k) be efficiently estimated, by using only values of g and points in dom(g)? A standard approach to these questions entails successively ehoosing a (prescribed) total of n>k points to be the abscissae for sequences of k-th divided differences,whose signs are then used to locate ...
