Hi alll,(adsbygoogle = window.adsbygoogle || []).push({});

I have an integral which includes a Kronecker delta:

[tex]

I = \int_{u=0}^{a} \int_{v=0}^{a} F(u) G(v) \delta_{u,v} \, \mathrm{d}u \, \mathrm{d}v

[/tex]

I know that for a 1D integral there exists the special property: \int F(u) DiracDelta(u-a) = F(a)

However, is there something equivalent for the problem I have stated in the first equation? I was thinking perhaps that:

I = \int F(u) G(u) du dv or something similar....

Cheers,

Natski
