comment Integral of harmonic function in a ball
Also, I know the Green's identity: $\int_{\Omega} \Delta u dx = \int_{\partial \Omega} \frac{\partial u}{\partial n} ds$, but I was a little confused with the expression "by calculating the line integral". Thank you.

comment Differential vs difference equations in mathematical modeling
Well, I don´t know if this is a meaningful divide. But my question is more about advantages and disadvantages in modeling, not only in the methods of resolution. Thank you all.

comment If $a>0,b>0$ show that exists $x,y\in \mathbb{I}$ near to $a,b$ such that $x^y\in \mathbb{Q}$
Thanks! On the other hand, the function $f$ is not helpful?
