Semiclassical resonance asymptotics for systems with degenerate crossings of classical trajectories

Marouane Assal, Setsuro Fujiié, Kenta Higuchi

This paper is concerned with the asymptotics of resonances in the semiclassical limit $h\to 0^{+}$ for $2\times 2$ matrix Schrödinger operators in one dimension. We study the case wh…
