A Local Levinson Theorem for Compact Symmetric Spaces
Journal of Lie theory, Tome 29 (2019) no. 3, pp. 787-8
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.
