      abstract     = {Block copolymers adsorbing to an interface between two
                      immiscible homopolymers modify the elastic constants of this
                      interface. Within self-consistent field calculations for
                      Gaussian chains, we determine how the bending constants vary
                      in dependence on the block copolymer concentration and
                      architecture. Four phenomena are discussed. (i) When a
                      tricritical or isotropic Lifshitz critical point is
                      approached in a ternary mixture by varying the concentration
                      of diblock copolymers or changing temperature, the elastic
                      constants vanish. We determine the corresponding power laws,
                      and show that the de Gennes-Taupin criterium for the
                      stability of lamellar phases against undulations and the
                      Ginzburg-Landau criterium for bulk fluctuations yield
                      identical predictions for the validity of the mean-field
                      approximation. (ii) Addition of a small amount of diblock
                      copolymers modifies the bending rigidity. If the diblock
                      copolymers are comparable in length to the homopolymers,
                      adsorption of the diblocks reduces the bending rigidity. If
                      the diblocks are much longer, they increase the bending
                      rigidity. Only for an extreme ratio of chain lengths (>100),
                      the predictions for polymers tethered to an infinitely thin,
                      impenetrable sheet become accurate. (iii) Mixtures of short
                      and long symmetric diblock copolymers are studied, as well
                      as mixtures of two asymmetric diblocks, which are obtained
                      by exchanging the long and short ends. The saddle-splay
                      modulus is found to be the same in both mixtures, while the
                      bending rigidity is significantly smaller in the latter
                      case. (iv) The role of the block copolymer architecture is
                      studied by comparing the effect of triblock copolymers with
                      the effect of diblocks with the same overall length and
                      composition. We propose that triblock copolymers are a very
                      efficient way to control the spontaneous curvature of an
                      interface.},
