What does the circumflex symbol mean in an expectation.

I am working with Pareto Distributions with parameters $\alpha$ and $\theta$.

I have the equation $$E(X \wedge Y)=\frac\theta{\alpha - 1}\left[1-\left(\frac\theta{\theta+Y}\right)^{\alpha - 1}\right]$$

What does the wedge mean in this case?
