Summary:
Sparse structures of dynamical systems induce decompositions of the Koopman and Perron-Frobenius operator. This is particularly the case for eigenfunctions and eigenmeasures for these operators. We extend such a result for invariant measures and illustrate at a numerical example how dynamic mode decomposition can benefit from exploiting sparsity.
