Abstract: The behaviour of D2-branes on the quintic under complex structuredeformations is analysed by combining Landau-Ginzburg techniques with methodsfrom conformal field theory. It is shown that the boundary renormalisationgroup flow induced by the bulk deformations is realised as a gradient flow ofthe effective space time superpotential which is calculated explicitly to allorders in the boundary coupling constant.
