Query: Quark confinement and curved spaces   In this work it will be shown how quark confinement appears when wave
equations derived in curved spaces are considered. First, the equations and
their solutions for Coulomb-like potentials will be presented, and then, how
this theory leads to quark confinement. A comparison between different models
of confinement will be also made.
