Dear All,
I' m here asking for some help with the following calculation:
$\sum_{r=0}^{3}\operatorname{Re}\left( \left( \alpha_{3,r}^{\ast}%
-\alpha_{4,r}^{\ast}\right) \left( \alpha_{2,r}e^{-i\phi_{r}}-\alpha
_{1,r}e^{i\phi_{r}}\right) \right) =2\sqrt{2}$
$\sum_{r=0}^{3}\alpha_{j,r}\alpha_{k,r}^{\ast}=\delta_{j,k}$ with
$j,k=1,2,3,4$
$\sum_{j=1}^{4}\left\vert \alpha_{j,r}\right\vert ^{2}=1$ for $r=0,1,2,3$
Is Mathematica able to find solutions?
In case of affirmative answer, how do I program Mathematica for this task?
Apologies, in the case my question is in some way naive.
Thanks,
Simone
