Schur parameters and Carathéodory class
Ming Li, Toshiyuki Sugawa
The Schur (resp. Carathéodory) class consists of all the analytic functions on the unit disk with (resp. and ). The Schur parameters $γ_0,γ_1,\dots…
A note on successive coefficients of convex functions
Ming Li, Toshiyuki Sugawa
In this note, we investigate the supremum and the infimum of the functional for functions, convex and analytic on the unit disk, of the form $f(z)=z+a_2z^2+a_3z…
Analytic and geometric properties of open door functions
Ming Li, Toshiyuki Sugawa
In this paper, we study analytic and geometric properties of the solution to the differential equation with the initial condition for a give…
Some extensions of the Open Door Lemma
Ming Li, Toshiyuki Sugawa
Miller and Mocanu proved in their 1997 paper a greatly useful result which is now known as the Open Door Lemma. It provides a sufficient condition for an analytic function on the u…
