Dr Vadim B. Kuznetsov, an expert in integrable systems, died on 16 December 2005, aged 42.

This issue includes papers from the fields in which Vadim worked: separation of variables, classical and quantum integrable systems, orthogonal polynomials and special functions, and other related fields. The works presented here were mostly motivated by the research and organisational work done by Vadim Kuznetsov.

Some of the papers have brief recollections of the meetings with Vadim. See for instance the papers by Aratyn & van de Leur, Grünbaum, Hone, Koornwinder, Langmann, Loutsenko & Spiridonov, Mangazeev, Sinitsyn & Zhilinskii. Please see the paper by his first adviser Igor V. Komarov for Vadim's short biography and his list of publications.

The issue contains 56 papers with the total of 957 pages.

We would like to thank all the authors who have published papers in the issue, and to give our special thanks to all the referees for providing constructive reviews.
