摘要
最近二十多年来.会融衍生证券在全球范围内获得迅猛发展,期权定价问题越柬越引起国内外数学家、金融学家的广泛重视。给期权合理的定价是期权交易的中心问题,因为交易主要是通过比较实际市场价格和期权真正价值进行的。在所有的衍生证券定价中,期权定价的研究最为广泛。期权定价问题是会融数学中的核心问题之一。1973年美国金融学家Black和Scholes在有效市场和股票价格遵循几何Brown运动,且股票的预期收益率和波动率为常数的假设下,获得了著名的Black—Scholes期权定价模型。B—S模型其实是一种理想的状态,在现实市场中,它的一些假设往往不满足。本文在B1ack—Scholes模型的基础上,通过改变B—S模型的基本假设,给出了几种基本的修ni模型及定价公式。改进后的模型使得股票价格行为更接近现实市场的运作规律,从而更有现实意义。

The evolution of black hole states
We discuss the evolution of black hole transients on the basis of a few systems that were intensively observed with the Rossi X-ray Timing Explorer. We focus on the global evolution and the observed state transitions. Rather than giving a numerical recipe

Black Holes and the Holographic Principle
This lecture reviews the black hole information paradox and briefly appraises some proposed resolutions in view of developments in string theory. It goes on to give an elementary introduction to the holographic principle.

I’d Rather Be Black than Female

Lesson 5: I’d Rather Be Black than Female
Being the first black woman elected to Congress has made me some kind of phenomenon. There are nine other blacks in Congress; there are ten other women. I was the first to overcome both handicaps at once. Of the two handicaps, being black is much less of a drawback than being female.
If I said that being black is a greater handicap than being a woman, probably no one would question me. Why? Because “we all know” there is prejudice against black people in America. That there is pre
Pulsars Tracing Black Holes in Globular Clusters
Results of precise measurements of the periods of pulsars discovered in the central regions of globular clusters are shown to be approaching the capabilities of testing the existence of a central black hole. For example, in the case of M 15 the available d
