Let $S$ and $T$ be two linear transformationtransformations on $\mathbb{R}^n$. We can find the eigen valueeigenvalues and eigen vectoreigenvectors of $S$ and $T$. I tryam trying to find out the realtionrelation(s) among the eigan valueeigenvalues and eigan vectoreigenvectors of $S$, $T$ and $S\circ T$. Is there any relation of this kind.
Thank you.?
