Title: Positivity in Noncommuting Variables



Abstract: Free real algebraic geometry deals with noncommutative polynomials and matrix tuples where the said polynomials attain positive semidefinite values. The talk will start with a motivation from Hilbert's 17th problem and conclude with a convexity result that demonstrates intrigues of the noncommutative world.
