Spectra of averages of unitary representations of LCA groups

Guy Cohen, Michael Lin

The paper studies the spectrum of operators obtained by averaging unitary representations of locally compact Abelian groups with respect to a probability measure, establishing incl…

Doeblin's condition, $I ¨ $ -mixing and spectra of convolution operators on the circle

Guy Cohen, Michael Lin

We study the asymptotic behavior of Markov operators $P_{I^} ¼$ defined by convolution with a probability measure $I^¼$ on the unit circle $T$ . We prove that when $I^¼$ is adapte…
