This report is concerned with the asymptotic distribution of resonances in the semiclassical limit of a one-dimensional 2 × 2 semiclassical Schrödinger operator. We fix a real energy E0 and suppose that the first potential V1 has a simple well at this level so that P1 has eigenvalues subject to the Bohr-Sommerfeld quantization rule, whereas the second potential V2 is “non- trapping” so that P2 has only continuous spectrum near this level. In such a situation, resonances are expected to appear near E0 in the lower half complex plane.

Abstract
This report is concerned with the asymptotic distribution of resonances in the semiclassical limit of a one-dimensional 2 × 2 semiclassical Schrödinger operator. We fix a real energy E0 and suppose that the first potential V1 has a simple well at this level so that P1 has eigenvalues subject to the Bohr-Sommerfeld quantization rule, whereas the second potential V2 is “non- trapping” so that P2 has only continuous spectrum near this level. In such a situation, resonances are expected to appear near E0 in the lower half complex plane.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
