Vladimir Retakh Rutgers University Algebra of pseudo-roots of noncommutative polynomials and noncommutative symmetric functions Friday 21st, March 12:05-12:55pm, Stephen Roberts. The elements arising in factorizations of a noncommutative polynomial into a product of linear factors are called its pseudo-roots. We are going to introduce an universal algebra of such pseudo-roots and to decribe its properties including its relations to noncommutative. symmetric functions
