Energy Preserving Discrete Line Integral Methods

Hamiltonian BVMs (HBVMs) constitute a class of energy-preserving methods for the numerical solution of canonical Hamiltonian systems, i.e., problems in the form:

where  J  is a constant skew-symmetric matrix, and  H(y)  is the Hamiltonian function. Such methods are able to preserve, in the numerical solution, the value of the Hamiltonian function, as it happens for the continuous one.  Hereafter, are the main facts about HBVMs:
