1. Introduction. A ring R is said to be alternative if (xx)y = x(xy), (yx)x=y(xx) for all x, y of R. And R is a division ring if it has a non-zero element and the equations ax = b, ya = b have unique solutions x, y for a ^0; the existence of a unit is not postulated. Let R be an alternative ring without divisors of zero.1 If a, b are nonzero elements of R… (More)

Introduction. If £ is a group with a normal subgroup K one may form the quotient group E/K^M. Conversely, for preassigned groups K, M, there is the extension problem: to determine (in some sense) all groups E with K as normal subgroup such that E/K^M. Much progress has been made on this problem, particularly through the work of Baer [l, 2, 3] and the… (More)

Introduction. A. A. Albert [l, I I ] 1 has conjectured that there exist simple loops of every finite order except order 4. This conjecture is established in §1 by the construction of what we call hyperdbelian loops? In §2 other simple loops are constructed, in particular, loops of order 2 / + 1 with subloops of order/ . The concluding section of the paper… (More)

Introduction. In this paper we shall be concerned with the structure of the rational representation of certain sets of matrices, to which we give the name generalized Fischer sets. If K is any field, <j> any fixed automorphism of K, and A any matrix with elements in K, we use the notation A* for the 0-automorph of A ; that is, the matrix obtained from A by… (More)

It should be noted that the definition (introduced in [l]) of a normal endomorphism of a loop G is radically different from the usual definition for groups. Nevertheless (as shown in [2]) the two definitions are equivalent when G is a group. In particular, the present theorem generalizes one of Heerema [3]. We may add that in [2], by assuming that the loop… (More)
