"Quasianalyticity" is a common term for various phenomena when a uniqueness theorem valid for analytic functionscontinues to hold in some classes of non-analytic functions. The classical theory of quasianalytic classes of functionswas developed in the first half of the 20th Century by Denjoy, Carleman, Bernstein and Beurling. Since then, it becamea flourishing area connected with various areas of complex and harmonic analysis and spectral theory of operators.In particular, deep results were obtained in the 1970-s and the 1980-s by Dyn'kin and Volberg.

In recent 15-20 years, theory of quasianalytic classes found new unexpected applications in other areas of mathematicssuch as real algebraic geometry, o-minimal structures, dynamical systems.

Our purpose is to bring together mathematicians working in different areas of mathematics and interested in the quasianalyticity.
