In the mathematical text I've read, it says that [tex]\frac{e^{ikz}}{z^{2}+m^{2}}[/tex] has only one simple pole, that is, [tex]im[/tex], if [tex] k>0 [/tex]. Why?
Has it got 2 simple poles, [tex] I am [/tex] and [tex] -im [/tex] ?
Has it got 2 simple poles, [tex] I am [/tex] and [tex] -im [/tex] ?
