From the reports of the 1st edition:

"The objective of this publication is to give an explanation for ‘how algebraic geometry, Lie conception and Painlevé research can be utilized to explicitly resolve integrable differential equations’. … one of many major benefits of this e-book is that the authors … succeeded to provide the fabric in a self-contained demeanour with a variety of examples. consequently it may be extensively utilized as a reference ebook for lots of topics in arithmetic. In precis … a good ebook which covers many attention-grabbing matters in glossy mathematical physics." (Vladimir Mangazeev, The Australian Mathematical Society Gazette, Vol. 33 (4), 2006)

"This is an in depth quantity dedicated to the integrability of nonlinear Hamiltonian differential equations. The e-book is designed as a instructing textbook and goals at a large readership of mathematicians and physicists, graduate scholars and pros. … The e-book presents many beneficial instruments and strategies within the box of thoroughly integrable structures. it's a important resource for graduate scholars and researchers who wish to input the integrability conception or to profit interesting features of integrable geometry of nonlinear differential equations." (Ma Wen-Xiu, Zentralblatt MATH, Vol. 1083, 2006)

Av qi=-8qi for the motion of a particle of mass 1 in a potential field V on R n. 9. Let (M, {-, ·}) be a Poisson manifold and let H E :F(M). The vector field XH = {· , H} is called the Hamiltonian vector field associated to the Hamiltonian H and we write Ham(M, {· ,·}) := {XH I HE :F(M)} for the vector space of Hamiltonian vector fields. A function H E :F(M) whose Hamiltonian vector field is zero, XH = 0, is called a Casimir function or a Casimir and we denote Cas (M, {·, ·}) :={HE :F(M) I XH = 0} for the (vector) space of Casimirs.

A vector field. The pair (M, {·, ·}) is called a Poisson manifold. If we want to stress that M is real or complex we use the terms real Poisson manifold and complex Poisson manifold. In many cases we will deal with Poisson structures on the affine space M = Rn or M = en. In this case, the standard coordinates X1 ••• , Xn on M lead to structure functions Xij E :F(M), which are defined by Xij :={xi, Xj} (1 ~ i,j ~ n). 6) for alll ~ i, j, k ~ n. 7) for all F, H E :F(M), as can easily be verified.

22) implies that 4cos2 (Jii = aiiaii· Letting nii := ai;a;i we have that if i =I j then 0, 1, 2, 3 are the only possible values for ni;, since aii is a non-positive integer when i =I j. The Dynkin diagram of g is the graph with l nodes labeled by 1, ... , l such that the nodes i and j are joined with nii bonds. 22) shows that the two roots cannot have the same length). This way the Cartan matrix, and hence the whole structure of the simple Lie algebra, can be encoded in its Dynkin diagram. 1 (the labeling of the roots in the Dynkin diagram is the one that is used in most classical books on Lie algebras, in particular (37], (79] and (87]).
