Abstract.
The Lempert function for a set of poles in a domain of $\mathbb C^n$ at a point $z$ is obtained by
taking a certain infimum over all analytic disks going through the poles and the point $z$,
and majorizes the corresponding multi-pole pluricomplex Green function. We investigate
the precise behavior of the Lempert function as a set of three poles in $\mathbb C^2$
coalesces to the origin.
