The technique for efficiency measurement known as Data Envelopment Analysis (DEA) has been extended to allow on-discretionary inputs that affect production. Several methods exist for measuring efficiency to control these ...

Let  $xi=(Gtimes_{K} mathcal{G} / mathcal{K}, rho_{xi}, G/K,mathcal{G} / mathcal{K})$  be the associated bundle and $tau_{G/K}=(T_{G/K},pi_{G/K},G/K, textrm{R}^{m})$ be the tangent bundle of special examples of odd dimension ...

In this paper, we considered a class of semilinear elliptic equations and extended some results about the method of sub-supper solutions to obtain new results for the generalized semi-linear elliptic equations via Schauder's ...
