What may be meant by the $\wedge$ here? I am dealing with article
Two Moments suffice for Poisson Approximations: The Chen-Stein Method by Arratia, Goldstein and Gordon.
On page 11 there is an expression with a $\wedge$ appearing in it:


[...] $b_3'(1~\wedge~1.4\lambda^{-1/2})$ [...]


I do not know what this $\wedge$ means here.
Do you have an idea?

In probability, it is standard to use $x \wedge y$ for the minimum of $x$ and $y$ and $x \vee y$ for the maximum of $x$ and $y$.
See Durrett's Probability: Theory and Examples 3e's notation page (or similar) for more common probability notation.
