摘要：
We discuss the Krein-von Neumann extensions of three Laplacian-type operators-on discrete graphs, quantum graphs, and domains. In passing we present a class of one-dimensional elliptic operators such that for any n is an element of N infinitely many elements of the class have n-dimensional null space.
