FLUX-CONFINEMENT IN DILATONIC COSMIC STRINGS

We study dilaton electrodynamics in Bat spacetime and exhibit a set of global cosmic-string-like solutions in which the magnetic flux is con fined. These solutions continue to exist for a small enough dilaton ma ss but cease to exist above a critical value depending on the magnetic flux. There also exist domain wall and Dirac monopole solutions. We d iscuss a mechanism whereby magnetic monopoles might have been confined by dilaton cosmic strings during an epoch in the early universe durin g which the dilaton was massless.
