The operators are defined by the method of quadratic forms on suitable Hilbert spaces. The model also covers quantum graphs and discrete Laplace operators.en1846-388620114723734ElementC0 -semigroupDirichlet formGap diffusionPositiveQuantum graphSubmarkovianMathematikJournal Article10.7153/oam-05-51Other
