2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/52247We study a relation between topological quantum field theory and the Kodama (Chern-Simons) state. It is shown that the Kodama (Chern-Simons) state describes a topological state with unbroken diffeomorphism invariance in Yang-Mills theory and Einstein's general relativity in four dimensions. We give a clear explanation of "why" such a topological state exists.8 pages, no figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
