Abstract

We study the Wilson loops in three-dimensional QFT from the D-branes in the AdS₄×CP³ geometry. We find explicit D-brane configurations in the bulk which correspond to both straight and circular Wilson lines extended to the boundary of AdS₄. We analyze critically the role of boundary contributions to the D2-branes with various topology and fundamental string actions.
