Density of states for the Anderson model on nested fractals
We prove the existence and establish the Lifschitz singularity of the integrated density of states for certain random Hamiltonians H ω = H 0 + V ω on fractal spaces of infinite diameter. The kinetic term H 0 is given by ϕ ( - L ) , where L is the Laplacian on the fractal and ϕ is a completely monoto...

where
L
is the Laplacian on the fractal and
ϕ
is a completely monotone function satisfying some mild regularity conditions. The random potential
