Abstract: We present some obstructions to certain Lagrangian surfaces' existence in R^4. The obstructions arise from studying moduli spaces of holomorphic disks with boundaries on the Lagrangian. From this, we deduce examples of pairs of knots that cannot be Lagrangian cobordant and knots that cannot bound Lagrangian disks.
