Topic of the Workshop

   The investigation of zeta functions has a fundamental place in many areas (number theory, arithmetic geometry,
group theory, mathematical physics, graph theory, dynamical systems, partial differential equations...). Many problems 
from these areas
as problems of counting solutions of Diophantine equations can be reformulated in terms of analytic problems of
zeta functions like meromorphic continuation, description of poles, special values, etc...
This point of view allows using the powerful analytic and geometrical methods (residues, integral representations,
singularities, etc...) in these areas.

   The focus of the workshop will be on some recent advances in the study of zeta functions. We hope to help
the specialists in remote fields, linked by the use of zeta functions, to exchange their experience.
