Arithmetic/Geometry Summer Schools of Galatasaray University
are intended for advanced post-graduate students and researchers and is aimed at
introducing its audience to research in an active field. The 2007 Summer School
will consist of two sections, Arrangements & Local Systems and
Singularities. Historically these two fields are closely related, require the
same mathematical background and often similar tools are employed in their
study. The summer school will be followed by a workshop on Hyperplane
arrangements.
