二十世纪五十年代到六十年代施乐利用独占的pp技术垄断了超过90%的复印机市场。 佳能以N系列复印机进入复印机市场并迅速在行业中立足佳能推出创新的个人复印机,开辟了新的巨大市场并形成领导地位

1.Integrability Demand function x(p,w)(.d.) is HDO, satisfied Walras Law and have a substitution matrix S(p,w) is s.n.s.d. for any (p,w), if it's deduced by rational preference. And if we observed an x(p,w) satisfied such conditions, can we find a preference to rationalization(p,w)? That the integrability problem

Recursion-breaking an object down into smaller objects of the same typeis a ma- jor theme in mathematics and computer science. For example, in an induction proof we establish the truth of a statement()from the truth of the statement P(n-1). In pro- gramming, a recursive algorithm solves a problem by applying itself to smaller instances

1 The Number-Picking Game Here is a game that you and I could play that reveals a strange property of expectation. 3, First, you think of a probability density function on the natural numbers. Your distri- bution can be absolutely anything you like. For example, you might choose a uniform distribution on 1, 2, ... 6, like the outcome of a fair die roll. Or you might choose a bi- probability, provided that,...,n. You can even give every natural number a non-zero nomial distribution on 0, 1 he sum of all probabilities is 1

无穷级数: 一系列无穷多个数u1,2,3n…写成u1+u2+u3+…+un+… 就称为无穷级数,记为∑un。这仅仅是一种形式上的相加。 这种加法是不是具有‘和数呢?这个和数的确切意义是什么 呢?
