This volume comprises a set of lecture notes from the CIMPA Summer School, Arrangements
and Local systems and Singularities, held at Galatasaray University,
Istanbul, during June 11-22, 2007. The school was attended by 68 mathematicians,
35 of them from 19 countries outside Turkey. The Summer School was made up
of eleven short courses and five seminars presented by an outstanding group of
lecturers who covered a wide range of topics related to the concepts of arrangements,
local systems and singularities. The list of lectures of the workshop appears
below. Most members of the audience were graduate students or young researchers
and the primary purpose of the school was to introduce them, in particular those
from developing countries, to the many advances and opportunities in this widely
applicable field.
