The price is formulated as the value function of an optimal stopping problem, which is the value function of a stochastic control problem given by a non-linear second order partial differential equation. The theory of viscosity solutions is applied to solve the stochastic control problem such that the value function is also the solution of the corresponding Bellman equation. Under some regularity assumptions, the existence and uniqueness of the solution of the pricing equation are derived by the application of the Perron method and Banach Fixed Point theorem.展开更多

Computer information technology, with its advantages in low cost, high efficiency and high quality, has been widely popularized and applied in the enterprise development. In this paper, the core competitiveness of enterprises in the information age and the far-reaching influence of a creative, sustainable growth on the development of enterprises are analyzed mainly from the information-based application in enterprise management and the influence of informatization and networking on enterprise management.展开更多

We obtain tight bounds on the complexity, considered as a function of two variables simultaneously:the number of processors, the rquired precision.
