Abstract
Thorpe and Weaire have discovered a simple relationship between the density of states of a model Hamiltonian for a tetrahedrally bonded amorphous solid and the density of states of a much simpler Hamiltonian. Here is given a simple derivation of that result. The case of a compound semiconductor is also discussed.Keywords
