摘要

In this paper, we consider the spectral property of symmetric additive measure of Lebesgue type supported on two intervals in the plane. We give a sufficient condition for the spectral property of symmetric additive measure of Lebesgue type supported on two unparallel intervals. Further, we characterise the spectral property of symmetric additive measure of Lebesgue type supported on two parallel intervals.
