ABSTRACT
In this paper, we study the Dirichlet problem associated with infinity-Laplacian type equations that may exhibit anisotropic character. We identify a broad class of nonlinearities for which the problem may or may not admit viscosity solutions for any continuous boundary data. We also discuss comparison with Finsler cones, which may be of independent interest.

Notes
1 The condition is needed to ensure that in . If F satisfies (F-2), then the restriction on b is unnecessary as, according to Corollary 3.11, the equation holds in any open set that does not contain z.
2 In a forthcoming paper, it will be shown that the solution is unique when f is identically zero or never vanishes and does not change sign.
