WebWe adapt the Agmon method to control this tunneling effect for quantum graphs with Sobolev and pointwise estimates. It turns out that as a generic matter, the rate of decay is controlled by an Agmon metric related to the classical Liouville- Geen approximation for the line, but more rapid decay is typical, arising from the geometry of the graph.

WebThe Agmon metric is given by gE(x) := (V(x)− E)+ g(x). The degenerate metric gE is supported in the forbidden region ΩE and we denote the cor-responding Riemannian distance function by dE: ΩE × ΩE → R+.
