For this new edition, the text has been carefully revised and expanded; in particular, a new chapter has been added on the deformation and contraction of Lie algebras.
From the reviews of the first edition:
"Iachello has written a pedagogical and straightforward presentation of Lie algebras [...]. It is a great text to accompany a course on Lie algebras and their physical applications."
(Marc de Montigny, Mathematical Reviews, Issue, 2007 i)
"This book [...] written by one of the leading experts in the field [...] will certainly be of great use for students or specialists that want to refresh their knowledge on Lie algebras applied to physics. [...] An excellent reference for those interested in acquiring practical experience [...] and leaving the embarrassing theoretical presentations aside."
(Rutwig Campoamor-Stursberg, Zentralblatt MATH,Vol. 1156, 2009)
