Over the last 15 years important results have been achieved in the field
of Hilbert Modular Varieties. Though the main emphasis of this book is
on the geometry of Hilbert modular surfaces, both geometric and
arithmetic aspects are treated. An abundance of examples - in fact a
whole chapter - completes this competent presentation of the subject.
This Ergebnisbericht will soon become an indispensible tool for
graduate students and researchers in this field.
