could somebody help me?...

[eljose]

let be the symmetric function

G(x,s)=\frac{1}{exp(sx)-1}

then get the linear operator L so LG(x,s)=\delta(x-s)

Looks like what is wanted is what operator has G as it green function.

Yew that,s precisely what i want to know, for a G (green function given) calculate the operator that it satisfies
