      abstract     = {The electronic structure of ternary compounds Pb2Sb2Te5,
                      Pb2Bi2Te5, and Pb2Bi2Se5, which have a layered structure
                      that consists of nine-layer atomic blocks separated by van
                      der Waals gaps, has been theoretically studied. It has been
                      shown that all studied compounds are three-dimensional
                      topological insulators. The possibility of the existence of
                      a two-dimensional topological insulator has been found in
                      ultrathin (0001) Pb2Sb2Te5 and Pb2Bi2Te5 films. Oscillations
                      of the a"currency sign(2) topological invariant with an
                      increase in the film thickness have been observed in the
                      latter compound.},
