Eigenvalue Properties of Schrödinger Operators
Eigenvalue Properties of Schrödinger Operators
<!-- *** Custom HTML *** --> In Evans–Lewis [5] and Evans–Lewis–Saitō [6], [7], [8], [9] we have been discussing conditions for the finiteness and for the infiniteness of bound states of Schrödinger-type operators using geometric methods. Here the ideas and results obtained so far are summarized and presented in an …
