Different types of Lifshitz transitions are governed by topology in momentum space. They involve the topological transitions with the change of topology of Fermi surfaces, Weyl and Dirac points, nodal lines, and also the transitions between the fully gapped states.

PACS: 03.65.Vf Topological phases (quantum mechanics);
PACS: 64.70.Tg Quantum phase transitions.

Key words: Lifshitz transitions, Fermi surface, Weyl and Dirac points.
