Books on spin foam
WebThe spin foam framework provides an approach to the dynamics of loop quantum gravity that is both background independent and Lorentz covariant. The most suc-cessful model is the one proposed by Engle, Pereira, Rovelli and Livine (EPRL) [1–3] and independently by Freidel and Krasnov (-FK) [4]. The model is formu- WebResearch has evolved in two directions: the more traditional canonical loop quantum gravity, and the newer covariant loop quantum gravity, called spin foam theory. The most well-developed theory that has been advanced as a direct result of loop quantum gravity is called loop quantum cosmology (LQC).

WebSpin foam models are an attempt at a fully covariant formulation of Loop Quantum Gravity. The subject took off when the Hamiltonian constraint of Chapter 10 was developed and one tried to use it in order to define a path integral formulation of its ‘transition amplitudes’.
