# Lim sup counter example

Is it possible to find a counter example to argue this:

$\limsup\limits_{n\rightarrow \infty} (A_n \cap B_n)$ = $\limsup\limits_{n\rightarrow \infty} A_n \cap \limsup\limits_{n\rightarrow \infty} B_n$

where $A_n$ and $B_n$ are two sequences.

$$A_{2n}=B_{2n+1}=A\ne\varnothing,\qquad A_{2n+1}=B_{2n}=\varnothing$$ Still, an inclusion is always valid...
