RE: Your dissertation, Introduction to Spin Networks and Towards a Generalization of the Decomposition Theorem which is opened along side two other papers: (1) the 1999 work of John Baez, An Introduction to Spin Foam Models of BF Theory and Quantum Gravity and (2) the most current work of Muxin Han, Zichang Huang and Antonia Zipfel, Spin foam propagator: A new perspective to include a cosmological constant
Dear Hans-Christian Ruiz:
Your 2012 paper (dissertation) is very, very helpful. Thank you for putting it up on ArXiv.
The problem I have with the industry is the inability of its scholars to break free of the mindset within Hawking’s and Newton’s earlier formulations. Both are right about enough things, these Lucasian professors have conjured up an innate fear of disagreeing with either of them about the most important concepts. Their longstanding choke hold is their definition of the infinite. I am attempting to apply continuity-symmetry-harmony to bring the infinite back into our equations in a potentially useful way. Interesting or silliness?
Thanks again for all your work.
