PREFAC E

The workshop entitled Topology, Complex Analysis and Arithmetic of Hyperbohc Spaces

was held at the Research lnstitute for Mathematical Sciences on December 4

8 of 2006

1n this workshop, there were 22 talks concernmg with hyperbolic spaces Most of the

papers m this volume are based on the talks

I would hke to thank all the participants and speakers 1 would also 1ike to express my

gratitude to the RIMS for support of the workshop and the pubhcation of the proceedmgs
