Agmon metric

WebActually,semiclassical methods in higher dimension require new sophisticated tools such as the Agmon metric, microlocal calculusand ?-pseudodifferential operators. These tools have beendeveloped by Agmon, Hörmander and Maslov in the 1970s and since then a large number of mathematicians have contributed to this subject. InSects. Webª The Agmon metric depends on the potential and, as we shall show, the graph structure. The Agmon philosophy ª Basically, if ψ∈L2and the EVE is valid, you look for a function F>0 for which integration by parts identities imply Fψ∈L2. In …

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.
