Extremal problems in de Branges spaces: the case of truncated and odd functions
Emanuel Carneiro, Felipe Gonçalves
In this paper we find extremal one-sided approximations of exponential type for a class of truncated and odd functions with a certain exponential subordination. These approximation…

Extremal functions in de Branges and Euclidean spaces
Emanuel Carneiro, Friedrich Littmann
In this work we obtain optimal majorants and minorants of exponential type for a wide class of radial functions on . These extremal functions minimize the $L^1(\mathb…

Some sharp restriction inequalities on the sphere
Emanuel Carneiro, Diogo Oliveira e Silva
In this paper we find the sharp forms and characterize the complex-valued extremizers of the adjoint Fourier restriction inequalities on the sphere $$\big\|\widehat{f σ}\big\|_{L^{…
