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. Contents Quantum Groups and Quantum Algebras
