This page describes memorial initiatives and explains how you can assist and/or participate.
1. Another obituary published in math journal Algebra Universalis
||Dr. Bob Quackenbush (University of Manitoba) is the editor of a memorial issue of Algebra Universalis: Volume 53, Numbers 2-3 (August 2005). It complements the more comprehensive obituary published in ORDER by focusing on Ivan's time as a PhD student at the University of Manitoba.
Read Ivan Rival: 1947-2002 (Acrobat PDF, 126 Kb), by Dr. Quackenbush, that appears on pages 141-2.
2. ORDER: a bronze sculpture about the enterprising mind at work
||In late 2002, to honour Ivan's life and work, the family commissioned Montreal master sculptor Michel Binette to create a memorial bronze sculpture. Completed in November 2003, the sculpture was inspired by the cover graphic of the journal ORDER that Ivan founded in 1984. Visit ORDER: The Sculpture to see pictures and find out more.
3. Scientific obituary published in math journal ORDER
Dr. Dwight Duffus (Emory University, Atlanta), Ivan's first PhD student, is the editor of a special memorial issue of ORDER, the mathematics journal Ivan founded: Volume 20, Number 3 (September 2003).
Read Obituary: Ivan Rival (Acrobat PDF, 123 Kb), by Dr. Duffus, that appears on pages 173-183, and includes a complete list of Ivan's publications.
"[...] he loved ideas Ė mathematical, musical, literary, political. Indeed, there often seemed a tension between the scholar deeply involved in the historical undertaking that is mathematical research, and the entrepreneur and organizer who saw the final proving of ideas in their use. In both the scholarly and entrepreneurial spheres, Ivanís most important contributions hinged on his ability to define an agenda and excite the participation of colleagues, and on the boundless energy and drive that brought projects to completion and opened the next phase of inquiry." —Dr. Dwight Duffus

4. Beechwood Cemetery monument
In the fall of 2003, the Rival family erected a monument in Ottawa's Beechwood Cemetery, Ivan's final resting place. The black granite monument bears the inscription "Mathematician, Computer Scientist, Entrepreneur". Beechwood Cemetery's rolling hills, maple trees, evergreens and gardens give it the feel of a tranquil park. It is a place of quiet, restful beauty, perfect for a reposeful walk and silent reflection.
The memorial website is an ongoing project and we invite you to contribute. We are interested in learning how your life intersected with Ivan's. Of interest are not only his professional life as a mathematician and entrepreneur, but also who he was as a friend and mentor, and his political activities on campus (McMaster and Manitoba) in the late 1960s and early 1970s.
