Minimal commutant and double commutant property for analytic Toeplitz operators

María José González, Fernando León-Saavedra

In this paper we study the minimality of the commutant of an analytic Toeplitz operator $M_{\phi }$, when $M_{\phi }$ is defined on the Hardy space $H^2(\mathbb{D})$ and $φ\in H^\infty(\mathbb…
