A Local Levinson Theorem for Compact Symmetric Spaces
Department of Mathematics, Indian Institute of Technology, Bombay, India
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.
