The Sixth workshop on ``Numerical Ranges and Numerical Radii'', sponsored by the Auburn University, was held on June 7-8, 2002, in conjunction with the Tenth International Linear Algebra Conference, June 10-13, 2002. The workshop took place in Parker Hall, where the mathematics department is located, of Auburn University.

The two day meeting began with an opening remarks by Dr. Stew Schneller (Dean of the College of Sciences and Mathematics, Auburn University) and Dr. Michel Smith (Chair of the Department of Mathematics, Auburn University). Eighteen talks on different aspects of numerical ranges and radii were given. See program and abstracts in http://www.math.wm.edu/~ckli/pgm.pdf for details. A workshop photo was taken in front of the Parker Hall, and a workshop dinner took place in the evening on June 7 at the China Palace restaurant.

There were about three dozen participants for the workshop from more than ten different countries (see the appended list). Similar to the previous meetings, participants exchanged many ideas, results and problems on the subject in a very friendly atmosphere. Furthermore, it was announced that Numerical Range would be one of the themes in the ``Topics in Linear Algebra Conference'' held at Iowa State University, September 13-14, 2002. One may contact Leslie Hogben (lhogben@iastate.edu) or Yiu-Tung Poon (ytpoon@iastate.edu) for details. Moreover, the Seventh workshop on ``Numerical Ranges and Numerical Radii'' will take place in Coimbra, Portugal, in the summer of 2004, organized by Natalia Bebiano (bebiano@ci.uc.pt).
