We consider the existence of radially symmetric non-negative solutions for the boundary value problem -Au(x) = lf{u(x)) IMI < 1, x e RN{N > 2) u(x) = 0 ||*|| = 1 where X > 0, f(0) < 0 (non-positone), /' > 0 and / is superlinear. We establish existence of non-negative solutions for A small which extends some work of our previous paper on non-positone problems, where we considered the case N = \ ...

As the world has flattened, some forms of services have become easily traded across geographies, cultures, and cost structures. Many countries—most notably India and the Philippines— have accelerated their economic growth through thriving information technology (IT) and business process services exports.

The agricultural sector employs majorities in developing countries and it contributes greatly to the development of these countries. Unluckily, majorities of the farmers are smallholders living in isolated rural areas and thus lack approp...

The application of market mechanisms for the allocation of computing services is a demanding task, which requires bridging economic and associated technical challenges. Even if the market-based approach promises an efficient allocation of computing services, the wide heterogeneity of consumer requirements and the diversity of computational services on provider side are challenging the processes...

Developing the e-services has directed organizations to aspire to achieve more market share in the competitive market. Consequently, they must present their services in such a system that customers return to the website and apply the e-services of that organization. This matter has become a serious challenge in this field and has generated a notion such as e-loyalty that various factors affect ...

In a Fisher market, a market maker sells m items to n potential buyers. The buyers submit their utility functions and money endowments to the market maker, who, upon receiving submitted information, derives market equilibrium prices and allocations of its items. While agents may benefit by misreporting their private information, we show that the percentage of improvement by a unilateral strateg...
