I don't know the meaning of these:(adsbygoogle = window.adsbygoogle || []).push({});

1) [tex]sup_{B_\delta}|f(x,y)| [/tex]

Where [itex]B_\delta [/itex] is the ball of radius [itex]\delta[/itex].

2) [tex]\int \int _{R^2 \B _{\delta} } f(xy)dxdy[/tex]

I don't know what is [itex]R^2 [/itex]\B[itex] _{\delta} [/itex]

Please read my latex because the symbol really don't show correctly.
