    How to derive or verify Hartree product?

    Happy summer...ish! I am reading the lecture/presentation at: http://fias.uni-frankfurt.de/~brat/LecturesWS1011/Lecture5.pdf In slide two, they outline the Hartree product, but can anyone give a hint about how it's derived, or how to verify it? Put another way, can someone give me...

    Runge-Kutta method for ut = f(x,y)?

    ^Thanks, I think that is probably what I was looking for! One bonus question, while we're at it. Is there still value to using the RK method for the differential equation I listed in my previous post? That is, one with f(x,y), rather than f(t,x,y)?

    Runge-Kutta method for ut = f(x,y)?

    Sorry, how about something like the following? \frac{du}{dt} = x^2 + sin(y)

    Runge-Kutta method for ut = f(x,y)?

    Hi, I am trying to solve something similar to ut = f(x,y), and ut = f(t,x,y) using RK4. I asked a few friends, and nobody knew for sure how to go about it. I've also looked online, without much success. Can anyone give me a hint on this one? In reality, it is probably preferable to...

    Question about plasma ignition

    Hi, I am an EE studying some plasma physics. I am doing alright with it, but this question cropped up in my head a few days ago, and I've come to find out that most text-books don't devote a lot of time to it. I am interested in microfabrication, and plasma reactors are central to a lot...
