Title:Two Combinatorial Problems in Ring Theory
Seminar:Algebra and Number Theory Seminar
Speaker:Ed Formanek, Penn State University
I will give the history of two open problems in ring theory which may be related. The Nagata-Higman Problem. What is the least integer d(n) such that {x_1 \cdots x_{d(n)} is a linear combination of n-th powers in Q, the free associative algebra (without unit) in countably many variables? What is the least integer c(n) such that M_n(Q) has a non-vanishing central polynomial of degree c(n)?
