The equivalence of the direct adc approach and the eco-isr formulation rests on two common key features. The first is the so-called canonical pt order structure of the secular matrix [1], establishing the compactness of the nth-order isr-adc approximation schemes. The other is the separability [2] of the secular matrix with respect to two (or more) non-interacting sub-systems, which warrants size-consistency. While in the adc context these features could have been substantiated using… CONTINUE READING
