Weighted Clement - Type Interpolation Anda

One of the main mathematical tools in the residual based a posteriori error analysis is a weak interpolation operator due to Cl ement. Based on a partition of unity, we introduce a modiied weak interpolation operator which enjoys a further orthogonality property. As a consequence , the volume contribution in standard residual based a posteriori error estimates can be replaced by a smaller one w...

Optimal Policy in OG Models

In the present paper general stationary overlapping generations economies with many commodities in every period and many different consumers in every generation are considered. A government maximizes a utilitarian social welfare function, which is the sum of weighted averages of utilities for generations, through fiscal policy, i.e., monetary transfers and taxes. Situations both with and withou...

Landau ' s Inequalities for Tournament Scores anda

Ao and Hanson, and Guiduli, Gyy arff as, Thomass e and Weidl independently, proved the following result: For any tournament score sequence S = (s 1 ; s 2 ; : : : ; s n) with s 1 s 2 s n , there exists a tournament T on vertex set f1; 2; : : : ; ng such that the score of each vertex i is s i and the sub-tournaments of T on both the even and the odd indexed vertices are transitive in the given or...
