## Main Question or Discussion Point

hello,

given is the Operator L=[tex]\widehat{1}[/tex]+|u><v|, where [tex]\widehat{1}[/tex] means the unity-tensor.

Whats the inverse of L?

I calculated the inverse of L in R^2 but I dont get it back to the bra-ket-notation. Can somebody help?

BTW: Sorry for my bad english!
