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?
