In the usual framework of continuum games with externalities, we substantially generalize Coumot-Nash existence results [Balder, A unifying approach to existence of Nash equilibria, Int. J.Game Theory 24 (1995) 79-94; On ...

In this work, we propose some two-layer preference models that can be appropriately applied in management problems such as the group decision making about predicting the future market share of certain product. By introducing ...

The harvester ant Pogonomyrmex mendozanus is endemic to the central Monte desert. In this region, extensive grazing reduces grass cover and seed abundance in the soil bank. In previous studies carried out in ungrazed areas, ...

Nowadays, the representation and the treatment of color images are still open problems. Mathematical morphology is the natural area for a rigorous formulation of many problems in image analysis. Moreover, it comprises ...

We prove non-emptiness of the alpha-core for balanced games with non-ordered preferences, extending and generalizing in several aspects the results of Scarf (1971), Border (1984), Florenzano (1989), Yannelis (1991) and ...
