The applications of spinors in field theory and relativistic mechanics of continuous media are considered. The main mathematical part is connected with the study of invariant algebraic and geometric relations between spinors and tensors. The theory of spinors and the methods of the tensor representation of spinors and spinor equations are thoroughly expounded in four-dimensional and three-dimensional spaces. Very useful and important relations are derived that express the derivatives of the spinor fields in terms of the derivatives of various tensor fields. The problems associated with an invariant description of spinors as objects that do not depend on the choice of a coordinate system are addressed in detail. As an application, the author considers an invariant tensor formulation of certain classes of differential spinor equations containing, in particular, the most important spinor equations of field theory and quantum mechanics. Exact solutions of the Einstein–Dirac equations, nonlinear Heisenberg’s spinor equations, and equations for relativistic spin fluids are given. The book presents a large body of factual material and is suited for use as a handbook. It is intended for specialists in theoretical physics, as well as for students and post-graduate students of physical and mathematical specialties.PhysicsParticles (Nuclear physics)Quantum field theoryCosmologyMathematical physicsGeometry, AlgebraicMathematical Methods in Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19013Elementary Particles, Quantum Field Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P23029Cosmologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P22049Mathematical Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/M35000Algebraic Geometryhttps://scigraph.springernature.com/ontologies/product-market-codes/M11019Physics.Particles (Nuclear physics)Quantum field theory.Cosmology.Mathematical physics.Geometry, Algebraic.Mathematical Methods in Physics.Elementary Particles, Quantum Field Theory.Cosmology.Mathematical Physics.Algebraic Geometry.515.63Zhelnorovich Vladimir Aauthttp://id.loc.gov/vocabulary/relators/aut838599MiAaPQMiAaPQMiAaPQBOOK9910349500203321Theory of Spinors and Its Application in Physics and Mechanics2544751UNINA
