We show that properties of the induced dynamics can be obtained by studying boundary operators in the corresponding boundary space induced by the vertices of the graph. In particular, we characterise unitary dynamics and contractive dynamics. We demonstrate our results on various special graphs, including those recently treated in the literature.enGenerators of C -semigroups 0Linearised KdV-equationMetric graphsAllgemeines, WissenschaftBook Part10.1007/978-3-319-75996-8_25Other
