On the minimum of $I ¨ $ -Brjuno functions

Ayreena Bakhtawar, Carlo Carminati, Stefano Marmi

$I ¨ $ -Brjuno functions were introduced in \cite{MaMoYo_06} as an interesting variant of the classical Brjuno function, where one substitutes the $lo g$ singularity at $x = 0$ with the…

Global and local minima of $I^\pm$ -Brjuno functions

Ayreena Bakhtawar, Carlo Carminati, Stefano Marmi

The main goal of this article is to analyze some peculiar features of the global (and local) minima of $I^\pm$ -Brjuno functions $B_{I^} \pm$ where $I^\pm \in (0, 1] .$ Our starting point is the re…
