Collaborations
Joel Lee Brenner was a member of the American Mathematical Society from 1936.
Beasley relates that he
- was a graduate student and [Brenner] was visiting the University of British Columbia in 1966-67. Shortly after arriving at UBC, Joel circulated a memo to all the graduate students, informing them that he had several open problems in various areas of mathematics and would share them with willing students. Hoping to get a problem in group theory that I might work into a thesis, I went to his office and inquired about the problems. He presented me the Van der Waerden conjecture, which he informed me would be quite difficult, and after defining the permanent for me sent me off with several problems concerning the permanent function. His encouragement and enthusiasm persevered through several "proofs" of the Van der Waerden conjecture, and soon some of the less well-known problems had been solved. He would always tell me how a proposed attack would work and leave me to fight out the details. Those exchanges led to the publication of my first paper, and I became his thirteenth coauthor. By the time Joel had left UBC in the spring of 1967, I was firmly entrenched in matrix theory.[3]: 3
In 1981 Brenner and
- Let P(z) be a non-constant polynomial with complex coefficients. Then there is a positive number S > 0, depending only on P, with the following property:
- for every δ > 0 there is a complex number z such that |z| ≤ S and |P(z)| < δ .
Brenner ultimately acquired 35 coauthors in his publications.
