Analytic properties of moments matrices

摘要: Abstract Associated with each matrix element of the Generalized Moments Expansion, GMX ( n , m ) there is a unique expansion for ground state energy in terms “connected moments” I k Hamiltonian. That is, any set { } polynomial 's may be generated to desired order L, which dependent upon highest moment calculated. Here we wish study eigenvectors and eigenvalues itself. Furthermore investigate interplay between L determining combination yields “best” (i.e. most convergent) result energy.
