A Schwarz-Jack lemma, circularly symmetric domains and numerical ranges
A Schwarz-Jack lemma for functions with positive-real-axis maximum modulus yields monotonicity and convexity results for conformal maps on symmetric domains and a new proof of Crouzeix's theorem for 2x2 matrix numerical ranges.
