    "abstract": "The methods which are actively used for electronic structure calculations of\nlow-lying states of heavy- and superheavy-element compounds are briefly\ndescribed. The advantages and disadvantages of calculations with the\nDirac-Coulomb-Breit Hamiltonian, Huzinaga-type pseudopotential,\nshape-consistent Relativistic Effective Core Potential (RECP) and Generalized\nRECP are discussed. The nonvariational technique of the electronic structure\nrestoration in atomic cores after the RECP calculation of a molecule is\npresented. The features of some approaches accounting for electron correlation,\nthe configuration interaction and coupled cluster methods, are also described.\nThe results of calculations on E113, E114, U and other heavy-atom systems are\npresented.",
