comment Topological methods in finance
Interesting premise: a market metric based on Jones polynomial! I wonder if its behavior differs much from standard correlation metrics. Based on your username, the paper is your own -- it would be polite to mention that in your answer.

comment A question about pricing convertible bond with two different underlying assets
You'll get a better-quality answer if you are more specific about the terms and conditions (T&C) of the bond. In particular, if the holder chooses to convert, is the mixture of assets the conversion happens into determined by the holder, the issuer, or a formula?

comment Usage of Brownian Bridge?
For scrambling, a good place to start would be Hinckernell's Quasi-Monte Carlo methods and their randomizations.

Use trees or other PDE discretization. Though you say they are "difficult" they are the right approach.

comment Are power contracts traded on any stock market?
Power contracts were always the domain of the theoreticians. I never saw one go through our exotics desk (though our software would have supported it, because it was so darn easy to put in the library).

I consider Tavella and Randall to be the best place to learn finite difference techniques for finance.

comment How to compare different volatility measures?
You need to define what you mean by best and explain more precisely to get an germane answer.

comment Weighted average implied optionlet/swaptions volatility
Even some traders use weighted averages of surface volatilities as an initial stab at pricing, so you can certainly get in the ballpark that way. The weighting to use would depend heavily on the terms of the contract that needs pricing. For example if it pays off only in low-strike regions you would not necessarily weight ATM vols the highest.
