They seek to convene leading experts and young scientists with special emphasis on contributions from Europe. The first ENUMATH meeting held in Paris (1995), and the series continued by the ones in Heidelberg (1997), J¨ yvask¨ yla (1999), Ischia (2001) and Prague (2003). This book collects the major part of the lectures given at ENUMATH 2005, that took place in Santiago de Compostela, Spain, from July 18 to 22, 2005. It contents texts of invit
