comment Diophantine equation with primitive nth root of unity
@Abhinav Kumar: Thanks a lot! You are right, so the problem now is if it is possible that $(-(\chi^k-1)/(\chi-1))^n = \pm 2$ (I think not) and, as you tell, this implies $\sqrt[n]{\pm 2} \in \mathbb{Q}(\chi)$.

comment Solved cubic Thue equation
@Beenakker I know that a computer program like Mathematica can solve my equation, however I prefer to find some reference in the literature because I need to solve this equation in an article of mine - and I think that many referees do not like the use of Mathematica in this way.

comment Irrationality measure of formal power series
@Gjergji Zaimi Thanks. I read that paper, however seems to me that they invented this notion of irrationality measure and no reference is given, about a general theory of it.

comment References for the Poincaré-Cartan forms
All right. The strange thing is that my colleague had told me that the Poincaré-Cartan form was invented after the mid-20th century, so I can definitely say that he is wrong.

comment References for the Poincaré-Cartan forms
@Bryant So you can confirm that Poincaré-Cartan forms was known (in it's modern form) before the twentieth century?
