Introduction To The Theory Of The Early Universe (Set)

Presents the theory of the evolution of density perturbations and relic gravity waves, theory of cosmological inflation and post-inflationary reheating. This title gives a detailed account of the established theory, with derivation of formulas. It is suitable for advanced undergraduate students and graduate students.

Theory Of Groups And Symmetries: Representations Of Groups And Lie Algebras, Applications

This book is a sequel to the book by the same authors entitled Theory of Groups and Symmetries: Finite Groups, Lie Groups, and Lie Algebras.The presentation begins with the Dirac notation, which is illustrated by boson and fermion oscillator algebras and also Grassmann algebra. Then detailed account of finite-dimensional representations of groups SL(2, C) and SU(2) and their Lie algebras is presented. The general theory of finite-dimensional irreducible representations of simple Lie algebras based on the construction of highest weight representations is given. The classification of all finite-dimensional irreducible representations of the Lie algebras of the classical series sℓ(n, C), so(n, C) and sp(2r, C) is exposed.Finite-dimensional irreducible representations of linear groups SL(N, C) and their compact forms SU(N) are constructed on the basis of the Schur-Weyl duality. A special role here is played by the theory of representations of the symmetric group algebra C[Sr] (Schur-Frobenius theory, Okounkov-Vershik approach), based on combinatorics of Young diagrams and Young tableaux. Similar construction is given for pseudo-orthogonal groups O(p, q) and SO(p, q), including Lorentz groups O(1, N-1) and SO(1, N-1), and their Lie algebras, as well as symplectic groups Sp(p, q). The representation theory of Brauer algebra (centralizer algebra of SO(p, q) and Sp(p, q) groups in tensor representations) is discussed.Finally, the covering groups Spin(p, q) for pseudo-orthogonal groups SO↑(p, q) are studied. For this purpose, Clifford algebras in spaces Rp, q are introduced and representations of these algebras are discussed.

Quantum Gravity: Proceedings Of The Sixth Moscow Quantum Gravity Seminar

This volume is composed of the proceedings of the Sixth Moscow Quantum Gravity Seminar, held in Moscow, Russia in June 1995. The seminar was a continuum of a series of seminars which have played a major role in the development and consolidation of the quantum gravity field.

Particles And Cosmology - Proceedings Of The International School

These proceedings contain both general reviews on particle physics, astrophysics and cosmology, and discussion on some specific topics. Emphasis is placed on such areas as: physics and instrumentation in solar neutrino experiments; and cosmic rays and cosmic ray neutrinos.

Quarks '92 - Proceedings Of The 7th International Seminar

The main aim of this volume is to deal with nonperturbative field theory with implications for baryon number violation at high energies and cosmology. Also, the volume contains some fresh results concerning anyons, lattice field theory, perturbative field theory and astrophysics.

Particles And Cosmology - International School

This volume contains papers on recent experiments in the fields of particles and cosmology.
