Abstract. We review some currently developing theoretical approaches to nuclear quadrupole-octupole (QO) deformations and dynamics. We depict the present status of the study of collective spectra within a model of axial QO vibrations and rotations, showing recent results of its full solution in the two-dimensional (2D) deformation space. Also, we illustrate the application of a deformed shell model (DSM) with BCS pairing to study the influence of QO deformations on the isomeric properties of heavy even-even nuclei.
