Title: On Laplacians on infinite metric graphs

Abstract: Laplacian operators on graphs have a long history and enjoy deep
connections to numerous branches of mathematics and mathematical physics.
Laplacians on metric graphs, which are also widely known as quantum graphs,
got a lot of attention during the last decades as simplified models of
complicated quantum systems. The main focus in this talk will be on the
self-adjointness problem (a.k.a. quantum completeness) for the
corresponding Laplacian. More specifically, we will discuss the
relationship between one of the classical notions of boundaries for
infinite graphs, graph ends, and self-adjoint extensions of the minimal
Kirchhoff Laplacian on a metric graph. The talk is based on joint works
with D. Mugnolo (FernUni Hagen) and N. Nicolussi (TU Graz).
