More on one-commodity market games

In this paper we present a new definition related to super-balanced games interpreted as a particular type of cooperative game with transferable utility (TU). A concept of solution is defined and an existence result is determined. The fundamental aim of the paper is to extend the results previously obtained by the same author.TU cooperative games, super-balanced coalition

Existence results for nonlinear elliptic problems on fractal domains

Some existence results for a parametric Dirichlet problem defined on the Sierpi\'nski fractal are proved. More precisely, a critical point result for differentiable functionals is exploited in order to prove the existence of a well determined open interval of positive eigenvalues for which the problem admits at least one non-trivial weak solution

Phase Diagram for Roegenian Economics

We recall the similarities between the concepts and techniques of Thermodynamics and Roegenian Economics. The Phase Diagram for a Roegenian economic system highlights a triple point and a critical point, with related explanations. These ideas can be used to improve our knowledge and understanding of the nature of development and evolution of Roegenian economic systems.Comment: 10 page

Optimality conditions and duality in multiobjective programming with invexity

(', ?)-invexity has recently been introduced with the intent of generalizing invex functions in mathematical programming. Using such conditions we obtain new sufficiency results for optimality in multiobjective programming and extend some classical duality properties
