On torsional rigidity and ground-state energy of compact quantum graphs
Delio Mugnolo, Marvin Plümer
We develop the theory of torsional rigidity -- a quantity routinely considered for Dirichlet Laplacians on bounded planar domains -- for Laplacians on metric graphs with at least o…

On fully supported eigenfunctions of quantum graphs
Marvin Plümer, Matthias Täufer
We prove that every metric graph which is a tree has an orthonormal sequence of Laplace-eigenfunctions of full support. This implies that the number of nodal domains of the $…
