Hausdorff and box dimensions of self-affine sets in a locally compact non-Archimedean field

Abstract

We consider affine iterated function systems in a locally compact non-Archimedean field . We establish the theory of singular value decomposition in and compute the box and Hausdorff dimensions of self-affine sets in , in generic sense, which is an analogy of Falconer’s result for the real case. In , the box and Hausdorff dimensions of self-affine sets can be obtained only when the norms of linear parts of affine transformations are strictly less than . However, in a locally compact non-Archimedean field, the same result can be obtained without the restriction of the norms.
