The classical Ray-Knight theorems for the Brownian motion determine the law of its local time process either at the first hitting time of a given value a by the local time at the origin,or at the first hitting time of a given position b by the Brownian *** extend these results by describing the local time process jointly for all a and b,by means of the stochastic integral with respect to an appropriate white *** result applies toμ-processes,and has an immediate application:aμ-process is the height process of a Feller continuous-state branching process(CSBP)with immigration(Lambert(2002)),whereas a Feller CSBP with immigration satisfies a stochastic differential equation(SDE)driven by a white noise(Dawson and Li(2012));our result gives an explicit relation between these two descriptions and shows that the SDE in question is a reformulation of Tanaka’s formula.

黑格尔是第一个把现代性上升为一个哲学问题的思想家,他热情欢迎现代性的到来,但同时对现代性中的内在分裂、矛盾和冲突有敏锐的把握,指出其存在着所有权不具普遍性、劳动异化、市民社会伦理丧失、大规模贫困对精神带来消极影响等方面的危机。黑格尔认为,当时的其他思想家对此问题的认识都存在偏差,所以主张对现代性予以政治伦理重塑:在逐步恢复伦理性的市民社会发展的基础上,社会必须继续进展到现代国家,才能真正对现代性加以政治伦理的重塑,即现代国家能够使个人的特殊性与国家的普遍性达到有中介的统一,这样个人的本质就在国家的政治生活中得到了塑造,所有权、个人的主观性、劳动的异化、贫困等问题都将得到有效解决。黑格尔对现代性的剖析体现了强大的思想力量,但其重塑方案终究只是一种理想化的设想。
