Abstract:
For an elliptic $p(x)$-Laplacian with a piecewise constant three-phase exponent $p$ in the plane with three phases joining at a point, a Harnack inequality is proved and the Hölder continuity of the solution is established.
Key words:
$p(x)$-Laplacian, Harnack inequality, Hölder continuity, Moser method, three-phase exponent.
