I suddenly remembered a study in Shanghai Book City, I met a complexity research (as if the level was not too good, at least algebra levels did not exceed the 4th grade of the class, and the analysis level should be OK.) Say that they are in this area the study.
According to him, only three papers worldwide (I have used Google search for four?), His thoughts are not mainstream ~~~~~~~~~~~~
However, since mentioning, I will write down: Refinement and coarsening of nash eqlilibium (from him to write to my paper head, the last word seems to be a little spelling error), it seems that it is very promising.
Because I have to go home, I haven't left Email in a hurry. I hope that if the people will marry this website, leave Mail, of course, if there is QQ, MSN, etc. can also stay.
