Alternating units as free factors in the group of units of integral group rings

Proceedings of the Edinburgh Mathematical Society, 2011
AbstractLet G be a group of odd order that contains a non-central element x whose order is either a prime p ≥ 5 or 3l, with l ≥ 2. Then, in $\mathcal{U}(\mathbb{Z}G)$, the group of units of ℤG, we can find an alternating unit u based on x, and another unit v, which can be either a bicyclic or an alternating unit, such that for all sufficiently large ...

The Group of Units

1998
We saw in Chapter 5 that for each n, the set Un of units in ℤn forms a group under multiplication. Our aim in this chapter is to understand more about multiplication and division in ℤn by studying the structure of this group. An important result is that if n = pe, where p is an odd prime, then Un is cyclic; following a commonly-used strategy, we shall ...

Human Groups as Units of Selection

Science, 1997
David Sloan Wilson The simple theory of natural selection predicts that an individual, whether human or animal, will act "selfishly" so as to maximize his or her genetic contribution to the next generation. But what of altruism, kindness, and generosity? Where do these traits fit into theories of survival of the fittest?
