Comment to “Remarks on modification of Helgason’s support theorem. II” by T. Takiguchi. (English) Zbl 1161.44300

Summary: We slightly extend a uniqueness theorem for generalized Radon transforms \(f\mapsto Rf\) proved by J. Boman [Contemp. Math. 140, 23–30 (1992; Zbl 0791.44003)], by giving sharp decay conditions on the function \(f\) at infinity.
