摘要
The problem of existence of non-trivial functions in quasi-analytic classes on a sphere that have zero integrals over all balls centered on a given set is investigated. The case where the set of centers is the union of two concentric spheres is completely studied. © 2013 Springer Science+Business Media New York.
