The talk will discuss the behavior of the spectral measure
at the edge of the spectrum for half line discrete Schroedinger
operators with slowly decaying monotone potentials. A central example
is the bottom of the spectrum for the potential V(n) = 1/n^b, where
0 < b < 1/2. This is joint work with Y. Kreimer and B. Simon.
