  The boost-invariant tunneling of particles along the hyperbolas of constant
invariant time, tau^2 = t^2-z^2, is included in the transport equations
describing formation of the quark-gluon plasma in strong color fields. The
non-trivial solutions of the transport equations exist if the boost-invariant
distance between the tunneling particles, measured in the quasirapidity space
eta=1/2 ln ((t+z)/(t-z)), is confined to a finite interval Delta eta. For
realistic values of Delta eta the solutions of the transport equations show
similar characteristics to those found in the standard approach, where the
tunneling takes place at constant time t. In the limit Delta eta -> infinity,
the initial color fields decay instantaneously.
