IRREDUCIBILITY OF COMMUTING VARIETY ASSOCIATED WITH (son+m, son⊕som)

The ground field k is algebraically closed and of characteristic zero. Let g be a reductive algebraic Lie algebra over k and σ an involutory automorphism of g. Then g = g0 ⊕ g1 is the direct sum of σ-eigenspaces. Here g0 is a reductive subalgebra and g1 is a g0-module. Let G be the adjoint group of g and G0 ⊂ G a connected subgroup with LieG0 = g0. The commuting variety of (g, g0) is the follow...

This Stranger, My Son

This is the story of how a conventional middle-class American household?a surgeon, his wife and three normal children?had first to recognise, then to cope with and, finally, to exclude, an abnormal family member. Tony was a beautiful child, the eldest, and apart from long hours of screaming for no apparent reason, he seemed a normal baby. His intellectual and motor development was average, but ...

Like father like son

The natural environment is in a state of constant flux and living organisms are perpetually challenged to adapt to these changes. Yet the mechanisms of adaptation, which lead to the development of new characteristics or behaviours, have troubled philosophers and scientists since the days of ancient Greece. In fact, it was not until 1859, when Charles Darwin (1809– 1882) published The Origin of ...
