Journal of Lie Theory 29 (2019), No. 3, 787--800 Copyright Heldermann Verlag 2019 A Local Levinson Theorem for Compact Symmetric Spaces Mithun Bhowmik Department of Mathematics, Indian Institute of Technology, Bombay, India mithunbhowmik123@gmail.com A classical result due to Levinson characterizes the existence of non-zero functions defined on a circle vanishing on an open subset of the circle in terms of the point-wise decay of their Fourier coefficients [Proc. London Math. Soc. (2), 41 (1936) 393--407]. We prove an analogue of this result on compact symmetric spaces. Keywords: Riemannian symmetric space, Fourier transform, Levinson's theorem.
