摘要
而j和z则随着在T处的停止时间而被限定为fj / T 2Þ 1⁄4 z / T 2Þ} 1⁄4 Y a.s.(对于过程也是如此,即定理B.4)。同样,在引理4.6中,第一个等式在ft, T}上成立,第二个等式在fu, T}上成立。同样,在定理4.3的证明的最后,关于E1⁄2Jðu2Þ1C和E1⁄2J0ðu2Þ1C的两个不等式被精确地表述为:E1⁄2Jðu2Þ1C # 1⁄2E1⁄2J0ðu2Þ1C þ E1⁄2jðuÞ1C>fu,T} þ E1⁄2j / T Þ1C>fu1⁄4T};E1⁄2J 0ðu2Þ1C # 1⁄2E1⁄2Jðu2Þ1C 2E1⁄2zðuÞ1C>fu,T} 2E1⁄2z / T Þ1C>fu1⁄4T};
and j and z are left limited along stopping times at T with fjðT 2Þ 1⁄4 zðT 2Þ} 1⁄4 Y a.s. (and the same remark holds in the case of processes, that is Theorem B.4). Similarly, in Lemma 4.6, the first equality holds a.s. on ft , T} and the second equality on fu , T}. Also, at the end of the proof of Theorem 4.3, the two inequalities concerning E1⁄2Jðu2Þ1C and E1⁄2J0ðu2Þ1C are precised as follows: E1⁄2Jðu2Þ1C # 1⁄2E1⁄2J0ðu2Þ1C þ E1⁄2jðuÞ1C>fu,T} þ E1⁄2jðT Þ1C>fu1⁄4T} ; E1⁄2J 0ðu2Þ1C # 1⁄2E1⁄2Jðu2Þ1C 2 E1⁄2zðuÞ1C>fu,T} 2 E1⁄2zðT Þ1C>fu1⁄4T} ;
期刊介绍:
Stochastics: An International Journal of Probability and Stochastic Processes is a world-leading journal publishing research concerned with stochastic processes and their applications in the modelling, analysis and optimization of stochastic systems, i.e. processes characterized both by temporal or spatial evolution and by the presence of random effects.
Articles are published dealing with all aspects of stochastic systems analysis, characterization problems, stochastic modelling and identification, optimization, filtering and control and with related questions in the theory of stochastic processes. The journal also solicits papers dealing with significant applications of stochastic process theory to problems in engineering systems, the physical and life sciences, economics and other areas. Proposals for special issues in cutting-edge areas are welcome and should be directed to the Editor-in-Chief who will review accordingly.
In recent years there has been a growing interaction between current research in probability theory and problems in stochastic systems. The objective of Stochastics is to encourage this trend, promoting an awareness of the latest theoretical developments on the one hand and of mathematical problems arising in applications on the other.
