    How to correctly convolve two delta functions?

    How do I correctly compute the convolution of two delta functions? For example, if I want to compute ##\delta(\omega)\otimes\delta(\omega)##, I should integrate $$\int_{-\infty}^\infty \delta(\omega-\Omega)\delta(\Omega) d\Omega$$ This integrand "fires" at two places: ##\Omega = 0## and...

    Poisson's Eq. with separable variables?

    Greetings- In trying to solve a thermal stress problem, I have encountered an inhomogeneous differential equation of the following general form: \nabla^2 \Phi(r,z) = F_r(r)F_z(z) Solving the homogeneous case is no problem, as it is kind of a classic. Is there a route to finding a particular...
