N2 - The symmetry of exchange interaction of charge carriers in semiconductor nanostructures (quantum wells and quantum dots) is analyzed. It is shown that the exchange Hamiltonian of two particles belonging to the same energy band can be universally expressed via pseudospin operators of the particles. The relative strength of the anisotropic exchange interaction is shown to be independent of the binding energy and the isotropic exchange constant.
