comment Looking for the functions $\alpha_n(x)$ that satisfy $\sum_{n=0}^{\infty} e^{i \alpha_n(x)}\frac{H_n(x)}{\sqrt{2^n n!}}=0$
@Mr.G The question focuses on real $\alpha_n(x)$, but I would be interested if you can find complex ones!

comment Constrained variational calculus: Are we allowed to make use of the constraint before taking variations?
@OccupyGezi Will there be any need for using Lagrange multiplier after imposing the constraint?

comment differential equation of the square root of a matrix
I am wondering why the trajectory lies in the commutant of the algebra generated by A and B. Consider $M(dt)$ where $dt$ is an infinitismal time step. $M(dt)=M(0)+A.M(0).B.dt$ why does this commute with $A$ and $B$ if $M(0)$ does ?

comment Mathematical problems having rational number solutions
@AndréNicolas In Diophantine problems, you narrow the domain of solutions right from the beginning to integers or rational numbers. What I am asking about is when the only solutions are rationals.

comment Mathematical problems having rational number solutions
@orlandpm An example of such problems would be, if it exists, polynomials having only rational roots. I am aware that some 2nd order polynomials with rational coefficients do so. I am seeking a more general class of problems.
