Hi
I have a question regarding notation. I have a function f(x, y), which I would like to integrate as
[tex]
\int_{x>0,y<x\frac{1}{\sqrt{\pi}}+1}{f(x, y) dxdy}
[/tex]
My question is very simple, and probably very silly: What there a notation which enables me to write the condition for the integral (x>0, y ...) in a much shorter version? I thought about defining a set myself called α, which is defined by this condition and then just write
[tex]
\int_{\alpha}{f(x, y) dxdy}
[/tex]
But I am not sure if I am allowed to do this. Even if I am allowed to do this, I don't know how to properly define the set. I would be very happy to receive some professional help.
Best wishes,
Niles.
