Some selected topics and results from my latest series of papers on the integrated perturbation theory for cosmological tensor fields will be presented (papers I-IV). The formalism is constructed on the basis of irreducible decomposition of tensors of any rank, identifying physical variables which are invariant under the rotation of coordinates system. Symmetic properties in the projected tensor fields, such as rotation, parity, flipping, and complex conjugate, are made explicit. In this talk, I will focus on the parity symmetries in observable tensor fields.
