This paper proposes a model aiming at decomposing the Net Final Value of project under certainty. It makes use systemic outlook: investor's net worth is regarded as dynamic system whose structure changes over time. On this basis, profitability index presented, here named Systemic Added (SVA), which lends itself to periodic decomposition: shares formally translate economic concept residual incom...

A self-learning algebraic multigrid method for dominant and minimal singular triplets and eigenpairs is described. The method consists of two multilevel phases. In the first, multiplicative phase (setup phase), tentative singular triplets are calculated along with a multigrid hierarchy of interpolation operators that approximately fit the tentative singular vectors in a collective and selflearn...
