Basic expansions of solutions to the sixth Painlevé equation in the generic case

We consider the sixth Painlevé equation for generic values of its four complex parameters. By methods of power geometry, we obtain those asymptotic expansions of solutions to the equation near the singular point x = 0 for which the order of the first term is less than unity. We refer to these expansions as basic expansions. They form 10 families and include expansions of four types, namely, power, power-logarithmic, complicated, and exotic. All other asymptotic expansions of solutions to the equation near the three singular points x = 0, x = 1, and x = ∞ can be computed from the basic expansions with the use of symmetries of the equation. Most of these expansions are new.
