| Abstract: | We discuss bound and anti‐bound states for 2×2 matrix Schrödinger operator. We analyze the Fredholm determinant for Hamiltonians that can be represented in a multi‐channel framework. Our analysis covers the whole and the half‐line problems. We obtain some results on counting anti‐bound states between successive bound states. Copyright © 2017 John Wiley & Sons, Ltd. |
