Proof of the Agler--McCarthy entropy conjecture
Jialin Lei, Teng Zhang
In 2021, J.~Agler and J.~E. McCarthy proposed a two-step programme toward the celebrated Krzyż conjecture. The first step is to prove an entropy conjecture for polynomials whose z…
Intersections of Convex Hulls of Polynomial Shifts and Critical Points
Teng Zhang
Let be a complex polynomial of degree . For each , let denote the convex hull of the zeros of , and let denote the convex hull of…
Angle duality and a gap principle for convex combinations of incomplete polynomials on the unit circle
Teng Zhang
In this paper, we establish an angle duality and a gap principle for convex combinations of incomplete polynomials, extending two results of Ge and Gonek in [IMRN, 2024].Our approa…
Sharp Schoenberg type inequalities and the de Bruin--Sharma problem
Quanyu Tang, Teng Zhang
In this paper, we confirm two conjectures proposed by Georgiev, Gómez-Serrano, Tao, and Wagner~\cite{GGTW25} on Schoenberg type inequalities of order , thereby providing a comp…
