AbstractWith the discovery of the topological phase of the research material the prediction and clas sification of these materials was carried out in terms of the so called topological protection The topology of electron states requires surface states to occur due to electromagnetic in teractions and the body mass is insulated This seemingly successful discovery conceals afundamental disadvantage and the small number of topological materials detected in relationto the materials previously identified in the databases Which could become a problem forfinding topology materials Therefore the goal is to present a complete theory of electronbands which creates a novel contraband theory of electrons This approach creates a linkbetween topology and topical chemical bonds This theory of topological quantum chemistryis based on the description of the graph theory of momentum space Inverted space anddescribing the theory of complementary groups in the real space provide a comprehensivedescription of the properties of band structures For all 230 groups of crystal symmetry weclassify possible band structures that are generated from local atomic orbitals and show thatnon redundant topologies are invisible Such a new stance theory opens up the recognitionof topological insulations and their further prediction 1 Key words group theory graph theory band structure topology atomic limit crystalline symmetry molecular orbitals atomic orbital topological quantum chemistry theory and topologicalinsulators
