# Norms in differential privacy

I know that perturbation should be proportional to the $$\text{L}_1$$-sensitivity of the function if someone wants ($$\epsilon,0$$)-differential privacy, and proportional to the $$\text{L}_2$$-sensitivity of the function if someone wants ($$\epsilon, \delta$$)-differential privacy for $$\delta > 0$$.

But why is that? Can anybody describe the intuition behind the use of these two norms? Or maybe share some resources?
