SPECTRAL ANALYSIS OF TIME CHANGES OF HOROCYCLE FLOWS
(AMER INST MATHEMATICAL SCIENCES-AIMS, 2012)
We prove (under the condition of A. G. Kushnirenko) that all time changes of the horocycle flow have purely absolutely continuous spectrum in the orthocomplement of the constant functions. This provides an answer to a ...
