# From invariance to self-similarity: The work of Michael Hochman on fractal dimension and its aftermath (Brin Prize article)

• M. Hochman's work on the dimension of self-similar sets has given impetus to resolving other questions regarding fractal dimension. We describe Hochman's approach and its influence on the subsequent resolution by P. Shmerkin of the conjecture on the dimension of the intersection of $\times p$- and $\times q$-Cantor sets.
