Wilson loops on M2-branes and M5-branes

We calculate configuration energies of stringlike membranes in M2- and M5-brane spaces. In the near horizon approximation these backgrounds reduce to AdS(4) x S-7 and AdS(7) x S-4 spaces and the dual theories are supersymmetric SU(N) gauge theories, in accordance with the AdS/CFT correspondence. In this case the stringlike configuration energy is identified with the quark and antiquark energy interaction in the dual theories. Far from the horizon the dual theory is more involved but anyhow we were able to calculate the stringlike configuration energy. For limiting regimes we find simpler solutions for which some potentials exhibit a confinement behavior while others are nonconfining.
