Quantum Gravity as a Quantum Field Theory of Simplicial Geometry,This is an introduction to the group field theory approach to quantum gravity, with emphasis on motivations and basic formalism, more than on recent results; we elaborate on the various ingredients, both conceptual and formal, of the approach, giving some examples, and we discuss some perspectives of future developments.作者: 未開化 時(shí)間: 2025-3-22 01:09 作者: Irremediable 時(shí)間: 2025-3-22 06:05 作者: capsaicin 時(shí)間: 2025-3-22 10:07

An Essay on the Spectral Action and its Relation to Quantum Gravity, theory of the gravitational field coupled to matter.

Asymptotic Safety in Quantum Einstein Gravity: Nonperturbative Renormalizability and Fractal Spaceteory is likely to be nonperturbatively renormalizable.
