An extremal problem and inequalities for entire functions of exponential type

A Chirre, D Dimitrov, E Quesada-Herrera… - Proceedings of the …, 2024 - ams.org
We study two variations of the classical one-delta problem for entire functions of exponential
type, known also as the Carathéodory–Fejér–Turán problem. The first variation imposes the …

Sign uncertainty and de Branges spaces

E Carneiro, T Ismoilov, AP Ramos - arXiv preprint arXiv:2408.01186, 2024 - arxiv.org
We investigate here the sign uncertainty phenomenon for bandlimited functions, with a
competing condition given by integration with respect to a general measure. Our main result …

Zeros of -Functions in Low-Lying Intervals and de Branges spaces

AP Ramos - arXiv preprint arXiv:2404.07832, 2024 - arxiv.org
We consider a variant of a problem first introduced by Hughes and Rudnick (2003) and
generalized by Bernard (2015) concerning conditional bounds for small first zeros in a family …
