Query: The $\infty(x)$-equation in Grushin-type Spaces   We employ Grushin jets which are adapted to the geometry of Grushin-type
spaces to obtain the existence-uniqueness of viscosity solutions to the
$\infty(x)$-Laplace equation in Grushin-type spaces. Due to the differences
between Euclidean jets and Grushin jets, the Euclidean method of proof is not
valid in this environment.
