# Definition talk:Cauchy Principal Value

Should I put a negative space in between $\operatorname{PV}$ and $\displaystyle \int$?
$\displaystyle \operatorname{PV}\int_{-\infty}^{+\infty} f \left({t}\right) \ \mathrm d t$
$\displaystyle \operatorname{PV}\!\int_{-\infty}^{+\infty} \! f \left({t}\right) \ \mathrm d t$, "\!"
