Query: On the stability of thin-shell wormholes in noncommutative geometry   This paper reexamines a special class of thin-shell wormholes that are
unstable in general relativity in the framework of noncommutative geometry. It
is shown that as a consequence of the intrinsic uncertainty these wormholes are
stable to small linearized radial perturbations. Several different spacetimes
are considered.
