Query: Warped Products and Yang-Mills equations on non commutative spaces   This paper presents a non self-dual solution of the Yang-Mills equations on a
non commutative version of the classical $R^4_q\backslash\{0\}$, so
generalizing the classical meron solution first introduced by de Alfaro, Fubini
and Furlan in 1976. The basic tool for that is a generalization to non
commutative spaces of the classical notion of warped products between metric
spaces.
