| [[Birman–Schwinger principle]] <small>(Eigenvalue transformation method)</small>

| In [[mathematics]] and [[physics]], the Birman–Schwinger principle is a useful technique to reduce the eigenvalue problem for an unbounded differential operator (such as a [[Schrödinger operator]]) to an eigenvalue problem for a bounded integral operator. It originates from independent work by [[Mikhail Shlyomovich Birman|M. Sh. Birman]] and [[Julian Schwinger|J. Schwinger]] in 1961.
