for a divergent series i can write an expression in the form:

[tex]\int_{R}dxC(x)w(x)e^{-ax} [/tex]

where a is a divegent quantity in the form [tex]a=ln\epsilon[/tex]

the qeustion is how i would apply renormalization? fact if we apply functional differentiation respect to e^{-ax} we get

[tex]C(x)w(x) [/tex] the divergent term magically disappears
