Crouzeix's conjecture is an interesting open problem in operator theory. The conjecture states that the numerical range W(A) of any bounded linear operator A in a complex Hilbert space is a (complete) 2-spectral set for A. In this second lecture, we will continue discuss the conjecture and some applications.
