We talk about the spectral properties of Schroedinger operators on perturbed lattices.The main topics are the non-existence or the discreteness of embedded eigenvalues,the limiting absorption principle for the resolvent,spectral representations,the S-matrix and the associated inverse problems.Our theory covers the square,triangular,diamond,Kagome lattices,as well as the ladder,the graphite and the subdivision.

We provide a new hierarchy of semidefinite relaxations for polynomial optimization which combines some advantages of the standard LP-and SDP-relaxations:(a)
