$H^{\infty}$ -calculus for semigroup generators on BMO

Tim Ferguson, Tao Mei, Brian Simanek

We prove that the negative infinitesimal generator $L$ of a semigroup of positive contractions on $L^{\infty}$ has a bounded $H^{\infty} (S_{η}^{0})$ -calculus on the associated Poisson semi…

Self-commutators of Toeplitz operators and isoperimetric inequalities

Steven R. Bell, Timothy Ferguson, Erik Lundberg

For a hyponormal operator, C. R. Putnam's inequality gives an upper bound on the norm of its self-commutator. In the special case of a Toeplitz operator with analytic symbol in the…
