Welcome to David Borwein at Ninety. This site is a tribute to the life-time work of this versatile mathematician.
The site contains information on his 90th birthday (March 24, 2014) and its celebration (April 16, 2014), a brief biography [PDF] (and a 2004 reminiscence [PDF] by a son), and a timeline featuring photos of David and his collaborators, along with a complete archive of David's papers.
David Borwein's work in mathematics has spanned well over six decades. He currently holds both an Emeritus and an Adjunct professorship at Western University in London Ontario, and is still actively engaged in research, particularly in the fields of classical analysis and summability theory.
