Abstract

Interest in inverse dynamical, spectral, and scattering problems for differential equations on graphs is motivated by possible applications to nano-electronics and quantum waveguides and by a variety of other classical and quantum applications. Recently a new effective leaf peeling method has been proposed by S. Avdonin and P. Kurasov for solving inverse problems on trees (graphs without cycles). It allows recalculating efficiently the inverse data from the original tree to smaller trees, “removing” leaves step by step up to the rooted edge. In this paper, the main step of the spectral and dynamical versions of the peeling algorithm, i.e., recalculating the inverse data for a “peeled tree” is described. Bibliography: 12 titles.
