Mar 20, 2011 at 9:43 | comment | added | Yemon Choi | Seva: you would need to restrict your attention to pairs of positive definite matrices | |
Mar 20, 2011 at 8:07 | comment | added | Seva | I would start with checking, using Maple or Mathematica, all pairs of matrices with integer entries between, say, -$10$ and $10$. If no counterexample is found, this is a string indication that your inequality is, indeed, true. | |

Mar 20, 2011 at 7:11 | comment | added | user13773 | It should be $\lambda_2$ for the second term in the right-hand side. | |

Mar 20, 2011 at 6:53 | comment | added | Yemon Choi | Presumably you have tried (and solved) the case where $A$ and $B$ commute... | |
Mar 20, 2011 at 6:52 | comment | added | Yemon Choi | On the right-hand side, do you really mean $\lambda_1$ both times? | |
