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.

Your other question is pretty hard to read. You'll probably get more responses if you use the LaTeX
 
I see how you use LaTex on the forum now - didn't know about the itex command. Thanks. Shall just start the thread again and try to be a bit clearer.
