Title: Small denominators in quasi-periodic operators

Abstract: This presentation will explore two approaches for tackling the small denominators problem in the analysis of quasi-periodic Schrödinger operators. We begin by applying a KAM (Kolmogorov-Arnold-Moser) type method to establish irreducibility. Following this, we discuss an alternative approach that leverages semi-algebraic geometry and Cartan-type estimates.
