Fixed odds bet
|

Q: Find a Black-Scholes closed formula to price this fixed odds bet. I want to win N if over the next M days, the P has a high-low range (exceeding/not exceeding) Q points. For example: I get $50 if over the next 5 days the FTSE100 has a high-low range exceeding 2 points. For example, if the FTSE100 has a range of low=5,251.41 and high=5,253.94 over the next 5 days, I get $50 (because high – low = 2.53 > 2).... more »

Analysis : Is there a name for this?
|

Hi, Suppose f and g are functions having the same domains such that f is monotonic increasing/decreasing on a given interval iff g is monotonic increasing/decreasing on that same interval. Is there a name for such pairs of functions? (I ask this question since it arises in stat estimation theory with... more »

Order theory question
|

Hi! It's seems a simple problem and I could solve it myself, but I want to share it with sci.math. Let A is a poset and let Z is its subset (Z is also a poset with induced order). Let S is a subset of Z, let t in A. Let "inf^Z S" is defined (narrowing our problem we could assume that Z is a complete lattice, but I want to consider the more general case).... more »

Hungary went through a regime change on Nov 20, 2009

With American police cars in the past in Hungary, in the past weeks they brought in the first Sheriff to take post. Since there was no resistance, they announced it all scale in Hungary. With this decision to bring in the Sheriff system to Hungary, on the same day today they announced a replacement of the Hungarian government system altogether... more »
