The representation of the generalized linear Euler sums with parameters

In this paper, by using residue method, we obtain the representations of some basic linear generalized Euler sums with parameters. Based on the linear generalized Euler sums with parameters, some new Euler sums are obtained and expressed in the closed forms. When the parameters of new Euler sums take special values, we can get some usual expressions of Euler sums. Moreover, the integrals of many special functions can be expressed as the Euler sums given in this paper.

On Separability of the Profit Function

The present paper is concerned with deriving conditions on technology which are required for additive separability of the associated profit function. The appropriate representation of technology in this case is the Luenberger shortage function. The paper shows that this function must be simultaneously input-and-output translation homothetic.
