Non-increasing order

We resolve these issues as follows. We show that a nonincreasing returns to scale (nrs) model is usually appropriate when modeling rational choice among investors. We show when multiple risk and return measures can justifiably be combined and identify some suitable measures. We show we need a nonlinear model to justify the assumption of convexity and to model diversification. We develop a method to approximate a solution to this model as accurately as needed using a sequence of linear models. Coherent measures of risk come up again and again in our discussion.

We gave a new criterion for graphical partitions. We derive a new recursion formula, which allows the computation of the number g(n) of graphical partitions of weight n for up to n 900.A partition of weight n is a nonincreasing sequence of nonnegative integers (1, 2, . . . , k, . . .) whose sum is n. The weight is denoted by ||. The number of nonzero elements in the sequence is the length of the partition denoted by l(). The set of all partitions of weight n is denoted by P(n).
