An extension of ergodic theory for Gauss-type maps
Haakan Hedenmalm, Alfonso Montes-Rodriguez
We propose an extension of ergodic theory which focuses on the identification of ergodicity in terms of the uniqueness of the invariant measure. We first explain the concept for th…

Perron-Frobenius operators and the Klein-Gordon equation
Francisco Canto-Martin, Haakan Hedenmalm, Alfonso Montes-Rodriguez
We study the non-uniqueness sets for solutions to the Klein-Gordon equation in 1 space dimension, for solutions whose Fourier transform is a finite complex measure absolutely conti…
