Topology and Liquid Crystals. crystals are structures in an intermediate state between a liquid and a rigid body. There is a certain ambiguity in the very term. True liquid crystals have both the properties of a crystal (orderliness of structure) and the properties of a liquid (fluidity).

Theory of Gauge Fields. basis for all contemporary theories of elementary particles is the concept of a field. For each elementary particle there is a corresponding quantum field, and the interaction of elementary particles is defined by the interaction of quantum fields.

Systems with Spontaneous Symmetry Breakingenon that unifies such physically different systems as liquid crystals, magnetism, and superfluid helium, is called . It underlies many contemporary concepts in the theory of elementary particles, the theory of phase transitions, and a number of problems of cosmology.
