Query: Gronwall's conjecture for 3-webs with infinitesimal symmetries   We study non-flat planar 3-webs with infinitesimal symmetries. Using
multi-dimensional Schwarzian derivative we give a criterion for linearization
of such webs and present a projective classification thereof. Using this
classification we show that the Gronwall conjecture is true for 3-webs
admitting infinitesimal symmetries.
