Witryna13 4 Singularity-based methods towards integra-bility In this section, we review a variety of singularity-based methods able to pro-vide some global elements of integrability. The singular manifold method of Weiss et al. [94] is the most important of them, but it is not the only one. A prerequisite notion is the singular part operator D, http://web.mit.edu/16.90/BackUp/www/pdfs/Chapter1.pdf
