Pablo Shmerkin
I am a Professor at the University of British Columbia (on leave from T. Di Tella University and Conicet). My pronouns are he/him.
My work generally spans the areas of fractal geometry, ergodic theory and analysis, although I am also interested in connections to probability and combinatorics.
In particular, my recent work is concerned with:
-
Geometric properties of (random and deterministic) fractals of dynamical, arithmetic and combinatorial origin. In particular, geometrical aspects of dynamical rigidity and smoothness of self-similar measures.
-
Combinatorial problems in fractal geometry (distance sets, direction sets, Kakeya-type sets, projection theorems, etc).
-
Applications of fractal geometry in ergodic theory and analysis.
-
Self-affine sets and the subadditive thermodynamic formalism.
