31. General covariance is a special case of gauge invariance . 32. This is actually the origin of the SU ( 2 ) gauge invariance . 33. Proved the invariance of plurigenera under deformations for all smooth complex projective varieties. 34. The third is local position invariance , which includes spatial and temporal invariance. 35. The third is local position invariance, which includes spatial and temporal invariance . 36. The symmetry is called general covariance or diffeomorphism invariance . 37. Thus any model that does not impose translational invariance is flawed by construction. 38. The HPP model lacked rotational invariance , which made the model highly anisotropic. 39. One can provide complete rotation invariance in shape contexts. 40. Modal logics are generally characterized by invariances under bisimulation.
