|A>=a|c>+b|d> where a and b are complex numbers. So, is it correct to say that <A|=a^{*}<c|+b^{*}<d| ? Regards.

they are both independent variables. U is much bigger than t, in the sense that t/U \rightarrow 0

Fixed. thanks.

Let U and t be independent real variable. In the limit: t/U \rightarrow 0 Can I say that t^2/U \rightarrow 0 too? Or I can compare only same powers of both? Regards.

Hello. How do I evaluate, in Mathematica, limits like this: "X+Y" when X is much bigger than Y, i.e., when Y/X->0. The unswer should be X+Y->X. Regards.

Hello. In Mathematica, I'm trying to find the eigenvalues and eigenvectors of a 10x10 matrices that is diagonalizable for sure. The matrix ix: {{0, 0, 0, 0, -2 t, -2 t, -2 t, -2 t, 0, 0}, {0, 0, 0, 0, -t, t, -t, t, 0, 0}, {0, 0, 2 U, 0, -t, t, -t, t, 0, 0}, {0, 0, 0, 2 U, -2 t, 2 t...

Thank you very much. :)

Hello. I got a 10x10 matrix that I know that has a block diagonal form. How can I put it in that form, using Mathematica? Regards, Marcus.
