Abstract

Introducing and studying the pattern frequency algebra, we prove the analogue of L\"uck's approximation theorems on L2L^2-spectral invariants in the case of aperiodic order. These results imply a uniform convergence theorem for the integrated density of states as well as the positivity of the logarithmic determinant of certain discrete Schrodinger operators.
