Darboux transformations of Jacobi matrices and Padé approximation
Darboux transformation, monic Jacobi matrix monic generalized
2011/2/22
Let J be a monic bounded Jacobi matrix associated with the function F. We construct a pair of the lower and upper triangular block matrices L and U such that J = LU and the matrix JC = UL is a monic g...

Parametric two-electron reduced-density-matrix (p-2RDM) methods have enjoyed much success
in recent years; the methods have been shown to exhibit accuracies greater than coupled cluster
with single ...
