Gap of the First Two Eigenvalues of the Schrödinger Operator with Nonconvex Potential
Shing-Tung Yau
We give a lower estimate of the gap of the first two eigenvalues of the Schrodinger operator with a nonconvex potential in terms of a distance associated with the potential. The re…

An Estimate of the Gap of the First Two Eigenvalues in the Schrödinger Operator
Shing-Tung Yau
We give a lower estimate of the gap of the first two eigenvalues of the Schrodinger operator in the case when the potential is strongly convex. In particular, if the Hessian of the…
