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?
