With applications in quantum field theory, general relativity and elementary particle physics, this three-volume work studies the invariance of differential operators under Lie algebras, quantum groups and superalgebras. This second volume covers quantum groups in their two main manifestations: quantum algebras and matrix quantum groups. The exposition covers both the general aspects of these and a great variety of concrete explicitly presented examples. The invariant q-difference operators are introduced mainly using representations of quantum algebras on their dual matrix quantum groups as carrier spaces. This is the first book that covers the title matter applied to quantum groups.

Eight highly technical studies explore a wide range of problems involved in investigating the short wavelength emission of the solar corona. The topics include the experimental results from solar X-ray investigations, the calculated excitation cross-sections for collisions of atoms and ions with charged particles, and spectra of plasmas.

In the book, an unconventional physical model of creation of the observed physical space from a finite set of special discrete objects, byuons is presented. The global space anisotropy associated with a cosmological vectorial potential appearing in the definition of byuons, as well as a new interaction due to this anisotropy, are predicted. Results of an experimental investigation of the proposed new interaction are given. A new method of power production based on the new interaction, as well as a new principle of motion of objects in nature with the use of physical space as a support medium, are advanced. The book is intended for the general reading public, physicists (theorists and experimenters), astrophysicists, engineers (specialists in space technology and power engineering), and physical students.

The articles in this exceptional book contain regular papers, extended papers and reviews, and thus vary in length and are useful for all kinds of audience. They describe, as the book's name suggests, HTSC models and methodologies. Physical models (like extended BCS model, bipolaron model, spin bag model, RVB (resonating valence bond) model, preformed Cooper pairs and antiferromagnetic spin fluctuation (AFSF) based models, stripe phase, paired cluster (spin glass (SG) frustration based) model, Kamimura-Suwa (Hund's coupling mechanism based) model, electron- plasmon interaction, electron- phonon interaction, etc.), theoretical methods (methodologies) (like generalised BCS-Migdal-Eliashberg theory, Hubbard model, t-J model, t-t'-U model, Hubbard-Holstein model, Fermi-, non Fermi- and marginal Fermi- liquid concepts, generalised Hartree-Fock formalism, etc.) and, experimental status and methodologies are all described there. For comparison with cuprates, fullerenes, ruthenates, organic-, non Cu-containing oxide-and conventional (elemental, A15)- superconductors, molecular crystals, nickelates, manganites, borides etc. are also discussed.
