# An integro-differential equation

by Sepideh Bakhoda   Last Updated September 23, 2018 12:20 PM

I want to solve this integro-differential equation

$$(f(x,y,z)-g(x,y,z)\partial_z^{-1}\partial_x)u(x,y,z)=h(x,y,z)$$

where $$f, g ,h$$ are known and $$u$$ is unknown. In addition

$$\partial_z^{-1}(\vec{p_1},\vec{p_2})=\theta(z_1-z_2)\delta(x_1-x_2)\delta(y_1-y_2)$$

where $$\theta$$ is Heaviside step function, $$\delta$$ is Dirac's delta function and $$\vec{p_i}=(x_i,y_i,z_i)$$.

Can someone point me in the right direction? How should I start to attach this problem? Is there a general way to solve this kind of equation? I would also be very grateful if you introduce me some references on solving these equations.
