Resource-bounded dimension is a complexity-theoretic extension of classical Hausdorff dimension introduced by Lutz (2000) in order to investigate the fractal structure of sets that have resource-bounded measure 0. For example, while it has long been known that the Boolean circuit-size complexity class SIZE α2n n has measure 0 in ESPACE for all 0 ≤ α ≤ 1, we now know that SIZE α2n
