I propose a general form for the boundary coupling of B-type topologicalLandau-Ginzburg models. In particular, I show that the relevant background inthe open string sector is a (generally non-Abelian) superconnection of type(0,1) living in a complex superbundle defined on the target space, which Iallow to be a non-compact Calabi-Yau manifold. This extends and clarifiesprevious proposals. Generalizing an argument due to Witten, I show that BRSTinvariance of the partition function on the worldsheet amounts to the conditionthat the (0,<= 2) part of the superconnection's curvature equals a constantendomorphism plus the Landau-Ginzburg potential times the identity section ofthe underlying superbundle. This provides the target space equations of motionfor the open topological model.Comment: 21 page
