# Green similar problem

i would like to find an operator G(x,s)=G(s,x) so LGx,s)=H(x-s) with H(x) Heaviside,s step function,and its inverse problem that,s it given a function G(x,s) obtain the Operator L,my question is how are the functions, a(x) b(x) and c(x9 related to the values of G(x,s) and its derivatives...
