I did'nt update here for three months. And a projection about string field theory, it's an interesting title. From it , CFT is very important in the string theory and string field theory. But i have one day in a week that can be used in this problem. I'm sad.
After i finish the fee's problem,
I will do my best on this question. And a note about polchinski' book will be released, the note contains the calculation's detail, Of caurse, it contains the first two chapters...

don't waste time on unimportant issue such as quantization .
回复删除keep moving forward. eg, you will learn the application of bc theory. they play the role of ghost field in string.
Have the whole picture at first.
btw , string theory is dying and ads/cft is crap, in my opinion.
Good luck.

thank you aqyzzy ^_^
回复删除string theory may not solve our main problems of physics, but it can give us the method, i think so.
