SCH’NOL’S THEOREM FOR STRONGLY LOCAL FORMS
, 708
"... Abstract. We prove a variant of Sch’nol’s theorem in a general setting: for generators of strongly local Dirichlet forms perturbed by measures. As an application, we discuss quantum graphs with δ or Kirchhoff boundary conditions. Dedicated to Shmuel Agmon on the occasion of his 85th birthday ..."
