A particular compensation-type solution of the main cosmological constant
problem has been proposed recently, with two massless vector fields dynamically
canceling an arbitrary cosmological constant \Lambda. The naive expectation is
that such a compensation mechanism does not allow for the existence of an
inflationary phase in the very early Universe. However, it is shown that
certain boundary conditions on the vector fields can in fact give rise to an
inflationary epoch.
