Einstein-Maxwell-Dirac equations

Einstein-Maxwell-Dirac equations are related to quantum field theory. The current [url=http://www.utsource.net/CAPACITOR VARIABLE.html]CAPACITOR VARIABLE[/url] Big Bang Model is a quantum field theory in a curved spacetime. Unfortunately, no such theory is mathematically well-defined; in spite of STRZ4479 this, theoreticians claim to extract information from this hypothetical theory. On the other hand, the super-classical limit of the not mathematically well-defined QED in a curved spacetime is the mathematically SIE20031 well-defined Einstein-Maxwell-Dirac system. (One could get a similar system for the standard model.) As a super theory, EMD violates the positivity condition in the Penrose-Hawking Singularity Theorem. Thus, it is possible STK795-815 that there would be complete solutions without any singularities-Yau has in fact constructed some. Furthermore, it is known that the Einstein-Maxwell-Dirac system admits of solitonic solutions, i.e., classical electrons and photons. This is the kind X802478-003 of theory Einstein was hoping for. EMD is also a totally geometricized theory as a non-commutative geometry; here, the charge e and the mass m of the electron are geometric invariants of the non-commutative geometry analogous to pi.
