The original Dunkl operators and the associated Laplacian were defined by Charles F. Dunkl in papers published in 1989 and 1988 respectively, The Dunkl operators and their various modifications have stimulated considerable developments in a number of fields. There have been applications in classical analysis, mathematical physics, special functions, Lie theory, quantum groups, algebra, probability theory, and geometry.

This issue is devoted to the 20th anniversary of Dunkl operators.

Possible topics for papers include

  • orthogonal polynomials and approximation theory in several variables;
  • special functions associated with root systems;
  • integral transforms and Fourier analysis;
  • exactly solvable quantum-mechanical models of Calogero-Moser-Sutherland type;
  • Hecke and Cherednik algebras and their representations;
  • quantum groups;
  • complex reflection groups and Clifford algebra;
  • random processes.
Papers in these or related topics, and which involve Dunkl operators or their generalizations, are solicited for this special issue.

How to Submit an Article to the Issue.

The length of an article is not limited.

Publication will be done only on the results of the peer review according to refereeing policy of SIGMA.
