Abstract
We find relative differential invariants of orders eight and nine for
a planar nonparallelizable 3-web such that their vanishing is necessary
and sufficient for a 3-web to be linearizable. This solves the Blaschke
conjecture for 3-webs. As a side result, we show that the number of
linearizations in the Gronwall conjecture does not exceed fifteen and give
criteria for rigidity of 3-webs.
