Query: Cantor combinatorics and almost finiteness   In this survey we give a concise introduction to a continuous version of
Borel combinatorics. Our approach will have a certain algorithm-theoretic
nature and we will give special emphasis to the notion of almost finiteness
introduced by Matui as a continuous analogue of Borel hyperfiniteness. We also
show how the theory can be used to study spectral convergence for graph
Laplacians.
