| Dec 1, 2014 at 9:21 | comment | added | Jason Starr | @RB: I posted the wrong link to the wrong question (too many windows open simultaneously)! Here is the correct question. | |
| Dec 1, 2014 at 8:06 | comment | added | R B | @JasonStarr - I'm not the poster of the question you mention, and I don't see a direct connection. My question is motivated by a game I'm studying, and the solution $t$ of this set of equations would be a symmetric equilibrium in the game ($t_i$ would be the prob. of playing the $i$'th strategy). | |

| Nov 30, 2014 at 23:20 | comment | added | R B | @fedja - Actually in my application I do need all $t_i$'s to be non-negative, I'll add a clarification, thanks ! | |
| Nov 30, 2014 at 18:14 | comment | added | fedja | You do not mind if some $t_i$ are negative, do you? | |
| Nov 30, 2014 at 16:03 | comment | added | R B | @IlyaBogdanov - true, thanks for the correction ! | |

| Nov 30, 2014 at 15:59 | comment | added | Ilya Bogdanov | In your second system, shouldn't there be $(1-t_i)^k$ instead of $(t_i)^k$? | |

| Nov 30, 2014 at 15:52 | comment | added | R B | @EmilJeřábek - yes, sorry for the confusion. I also had a mistake copying the equation to the site which is corrected now (replaced $t_i$ and $1-t_i$). Thanks again. | |

| Nov 30, 2014 at 15:47 | comment | added | Emil Jeřábek | Oh I see, so these are just brackets. | |
| Nov 30, 2014 at 15:42 | comment | added | R B | @EmilJeřábek - the $p_i$'s are given, the $t_i's$ are the variables and I meant the product of $p_i$ and $1 - t_i\ ^n$. I've edited the question, hope this is clear now, thanks. | |
