I posted a problem called "estimating eigenvalue of perturbed matrix" in the section 'Linear and abstract algebra' cus, well it was to do with matrices (I'm a physicist - appologies for that). Actually come to think of it the problem probably has more to do with analysis....If a kind maths peep could have a look I'd be grateful.(adsbygoogle = window.adsbygoogle || []).push({});
