Topic #1 ---------- OP-SF NET 14.1 ---------- January 15, 2007

From: OP-SF NET Editors

Subject: OP-SF NET format and delivery

Since its inception the version of OP-SF NET mailed to subscribers has been in a simple text format. This had the advantage of small file-size and no special software being needed by readers. With the passage of time these desiderata have become less crucial and we have begun to discuss alternate formats and modes of delivery. The present issue is being sent in two formats, the usual text-only format within the body of an email and a .htm version as an attachment. Comments on this change and further suggestions will be welcomed by the editors.

Topic #2 ---------- OP-SF NET 14.1 ---------- January 15, 2007

From: OP-SF NET Editors

Subject: Lee Lorch gets major MAA award

Lee Lorch, Professor Emeritus of Mathematics at York University, received the Mathematical Association of America's "Yueh-Gin Gung and Dr. Charles Y. Hu Distinguished Service to Mathematics Award" on January 6, 2007, during the Joint Mathematics Meetings in New Orleans. This award is the most prestigious award for service offered by the Association. It honors distinguished contributions to mathematics and mathematical education – in one particular aspect or many, and in a short period or over a career.

Lee Lorch's mathematical research has been in the areas of analysis, differential equations, and special functions. In the Award citation, he was described as a remarkable teacher of mathematics and an inspiration to his students and as a vocal advocate and energetic worker for human rights and educational opportunities for women and minorities.

In accepting the award, Lee wrote: "While this award honors me, it gives me even greater satisfaction that, by making it, the MAA emphasizes its support for equity." But he also noted that "this fight is far from over" pointing to the plight of Katrina and post-Katrina New Orleans.

Topic #3 ---------- OP-SF NET 14.1 ---------- January 15, 2007

From: OP-SF NET Editors

Subject: Preprints in arXiv.org

The following preprints related to the fields of orthogonal polynomials and special functions were posted or cross-listed to one of the subcategories of arXiv.org during recent months.

The items from September and October 2006 were inadvertently omitted from the original mailing of our November 15, 2006 issue but were added to some of the later issues.

Hence we give here four months worth of items.

We begin with November and December 2006 and follow these with those for September and October 2006

November and December 2006

Topic #4 ---------- OP-SF NET 14.1 ---------- January 15, 2007

From: OP-SF NET Editors

Subject: About the Activity Group

The SIAM Activity Group on Orthogonal Polynomials and Special Functions consists of a broad set of mathematicians, both pure and applied. The Group also includes engineers and scientists, students as well as experts. We have around 140 members scattered about in more than 20 countries. Whatever your specialty might be, we welcome your participation in this classical, and yet modern, topic.

Our WWW home page is:

http://math.nist.gov/opsf/

This is a convenient point of entry to all the services provided by the Group.

Our Webmaster is Bonita Saunders (bonita.saunders@nist.gov).

The Activity Group sponsors OP-SF NET, which is transmitted periodically by SIAM. It is provided as a free public service; membership in SIAM is not required.

The OP-SF Net Editors are Diego Dominici (dominicd@newpaltz.edu) and Martin Muldoon (muldoon@yorku.ca).

Given the widespread availability of email and the Internet, the need for the printed Newsletter has decreased. Discussions are underway concerning whether an annual printed Newsletter or Annual Report should be instituted.

SIAM has several categories of membership, including low-cost categories for students and residents of developing countries. For current information on SIAM and Activity Group membership, contact:
