报告摘要:
Self-affine measures arise as stationary measures of random walks driven by contracting affine maps on Euclidean spaces. Their dimensional properties play a central role in fractal geometry. In this talk, we establish that, under mild assumptions, the dimension of a diagonal self-affine measure is given by the minimum of the ambient dimension and its Lyapunov dimension. Our proof relies on techniques from ergodic theory and additive combinatorics..
