Jun 5, 2013 at 5:13 comment added liubenyuan So I need to prove $(\mathbf{B}_i^{-1} + \gamma_i\mathbf{s}_i)^{-1}\mathbf{B}_i^{-1}(\mathbf{B}_i^{-1} + \gamma_i\mathbf{s}_i)^{-1}$ was included in the subset $\mathbf{M}$ ?

Jun 4, 2013 at 17:47 comment added darij grinberg (If it is $\left[A,F\right]$ that Dietrich wanted to say, the result appears in C. Brookes' "Lectures on Lie Algebras", scribed by Eva Belmont people.ds.cam.ac.uk/eb525/lie-notes.pdf . It is Lemma 9.4 (3.25). The former number apparently can change while the latter is invariant. $x_s$ and $x_n$ are defined in Lemma 9.1 (3.22).)
Jun 4, 2013 at 17:42 comment added darij grinberg @Dietrich: Do you really mean $AF-FA$, not $\left[A,F\right]$ (which are different things, e. g., because $AF-FA$ is the same as $AF+FA$) ?

Jun 4, 2013 at 13:04 comment added Dietrich Burde $End(V)$ is the space of all linear maps $A\colon V\rightarrow V$ (square matrices, if you want).
Jun 4, 2013 at 12:43 comment added liubenyuan Sorry, dear Dietrich, I could not quite follow your answer. and what does End(V) mean ? Which book should I refer to ? However thanks for your answer, it seem like I could obtain $\mathrm{Tr}(B)=0$ with some additional constrains imposed on $\mathbf{A}$.
