Using the thermodynamical approach and the method of York, the back-reaction of extremal R-N black hole in thermal equilibrium is studied. It is found that both approaches give identical results. 相似文献

The contributions from anisotropic magnetic screening and electronic effects to the relative chemical shifts of the NH protons in the amides and N,N-dimethylhydrazides of succinic and glutaric acids were calculated. It was shown that the splitting of the signals of the NH protons is largely determined by the redistribution of electron density in the molecule during the conformational transition. 相似文献

We analyze a two-stage telecommunication supply chain consisting of one operator and one vendor under a multiple period setting. The operator faces a stochastic market demand which depends on technology investment level. The decision variables for the operator are the initial technology investment level and the capacity of the network for each period. The capacity that the operator installs in one period also remains available in subsequent periods. The operator can increase or decrease the available capacity at each period. For this model, an algorithm to find the centralized optimal solution is proposed. A profit sharing contract where firms share both the revenue and operating costs generated throughout the periods along with initial technology investment is suggested. Also a coordinating quantity discount contract where the discount on the price depends on the total installed capacity is designed. The case where the vendor decides on the technology investment level and the operator decides on the capacity of the network is also analyzed and it is shown that this game has a unique Nash equilibrium. 相似文献

In this paper, we introduce systems of simultaneous generalized vector equilibrium problems and prove the existence of their
solutions. As application of our results, we derive the existence theorems for solutions of systems of vector saddle–point
problems. Consequently, we prove the existence of a solution of systems of generalized minimax inequalities. Further application
of our results is also given to establish the existence of a solution of a Debreu-type equilibrium problem for vector-valued
functions.

In this note, we present a method that allows us to decide when a Markov-perfect Nash equilibrium is not Pareto optimum, without the explicit knowledge of the respective solutions. For that purpose, we establish a sufficient condition in terms of an algebraic inequality where the gradient of the value functions of the cooperative and noncooperative games as well as the state and control variables are involved. 相似文献

We study nonzero-sum stopping games with randomized stopping strategies. The existence of Nash equilibrium and ɛ-equilibrium
strategies are discussed under various assumptions on players random payoffs and utility functions dependent on the observed
discrete time Markov process. Then we will present a model of a market game in which randomized stopping times are involved.
The model is a mixture of a stochastic game and stopping game.
