The HÃ¶rmander--Bernhardsson extremal function

Andriy Bondarenko, Joaquim Ortega-CerdÃ, Danylo Radchenko +1

We characterize the function $I ¨ $ of minimal $L^{1}$ norm among all functions $f$ of exponential type at most $I ¨ $ for which $f (0) = 1$ . This function, studied by HÃ¶rmander and Bernha…

The HÃ¶rmander--Bernhardsson extremal function: A preliminary study

Andriy Bondarenko, Joaquim Ortega-CerdÃ, Danylo Radchenko +1

We study the function $I ¨ _{1}$ of minimal $L^{1}$ norm among all functions $f$ of exponential type at most $I ¨ $ for which $f (0) = 1$ . This function, first studied by HÃ¶rmander and Bernh…
