Cores of Combined
نویسندگان
چکیده
This paper studies the core of combined games, obtained by summing two coalitional games. It is shown that the set of balanced transferable utility games can be partitioned into equivalence classes of component games to determine whether the core of the combined game coincides with the sum of the cores of its components. On the other hand, for non-balanced games, the binary relation associating two component games whose combination has an empty core is not transitive. However, we identify a class of non-balanced games which, combined with any other non-balanced game, has an empty core. JEL Classification Numbers: C70, C71

Application of sediment cores in reconstruction of long-term temperature and metal contents at the northern region of the Persian Gulf
Long marine sedimentary cores can be effective in paleo-climate reconstruction. The present research aims at analyzing the temporal variation of temperature as an important climate parameter and also variations in metal concentrations (As, Ba, Cd, Li, Mo, Mg, Mn, Na, Pb, Sr, Zn, Fe, Ca, Al) of two long sedimentary cores at the Persian Gulf back to the Holocene. The obtained results revealed th...
متن کاملExplaining the Presence of Narrow-faced Bladelet Cores in Izeh Chipped Stone Assemblages and its relation to Population/Idea Movements in Late Pleistocene
Abstract: Several models of population/culture movements have been proposed based on bladelet production in Late Pleistocene of Eurasia. Narrow-faced bladelet/microblade cores, also known as "wedge shaped" cores in Central Asia and Far East studies, have been considered as a component of an inter-continent migration of people and idea which originated in Sibero-Mongolian region Upper Paleolithi...
متن کاملThe role of spatial changes of employment and activity in creating the lack of appropriate urban cores (case study; Tehran)
Background and objective: The spatial structure of cities depends on the different and mutual relationships of all forces and factors in the city. These factors include market forces, activities, urban infrastructures and various services, which always have a complex and reciprocal relationship. In today's world, one of the basic challenges in cities is to create a balanced spatial structure th...
متن کاملTHE EFFECT OF COSMIONS ON THE STABILITY OF MAIN SEQUENCE STELLAR CORES
We have studied the effect of hypothetical Cosmions on the core stability of main sequence stars (of populations I and II). Cosmions, with a mass of 4-10 Gev/c2 and a scattering cross section with nucleons of approximately 10-36 cm2 could prevail in transporting heat in the stellar cores. Raby [17] showed the existence of a local thermal instability caused by the presence of Cosmions in the sol...
متن کاملImprovement of Collapsibility of Sodium Silicate Bonded Cores for Aluminium Casting
This paper examines the compressive strength of sodium silicate bonded cores for aluminum casting with different additives. Various materials are used as additives among which it is found that 5% sand size bauxite has the best effect on both gas strength and de-coring 98.5% silica content sand with 70-90 AFS No. with 4% sodium silicate is used. The results indicate that although very good colla...
