Three of the leading figures in the field have composed this excellent introduction to the theory of Lie groups and Lie algebras. Together these lectures provide an elementary account of the theory that is unsurpassed. In the first part, Roger Carter concentrates on Lie algebras and root systems. In the second Graeme Segal discusses Lie groups. And in the final part, Ian Macdonald gives an introduction to special linear groups. Graduate students requiring an introduction to the theory of Lie groups and their applications should look no further than this book.

Reliable genealogical conclusions depend on reliable data. Central to any good investigation is an appreciation of where the data came from, so that other investigators can re-examine it and re-establish the conclusions reached. Genealogy is little more than anecdote when the sources for facts are not cited and where clear references to sources are not given. Referencing for Genealogists will enable others to follow in your footsteps because it gives you the means to write clear, unambiguous references that provide solid support to the evidence you offer towards your conclusions. It is packed with examples that the reader can learn from and that also provide a treasure trove of sources invaluable to any genealogist.
