This operator algebra lends itself well to quantum statistics, nevertheless, our physical understanding of this process is nonintuitive at best. In this paper we analyze the creation of fermions from primordial gauge field quantum gravity loops in the context of Calabi-Yau manifold theory. I extend a prior mass-gap treatment based on Yang-Mills gauge theory of higher order self-interaction to include the half-integral spin of fermions.展开更多

The purpose of this research is to apply these to a theory of gravity and develop the consequences of the model based on these tools. This paper presents such results without mathematical details, which are presented elsewhere. The tools are: Geometric Calculus, developed by David Hestenes, circa 1965 and Mathematica, released in 1988 by Steven Wolfram. Both tools have steep learning curves, requiring several years to acquire expertise in their use. This paper explains in what sense they are optimal.展开更多

The algorithms which extract simple spin coupling topologies from MQF-COSY, construct more complicated spin coupling topologies based upon MQ spectrum including all possible pathways, and extract spin coupling topological fragments for amino acids of a protein, have been implemented in C^(++) language and run on a SUN 4/280 work station. Compared with the manual assignments for melittin, the total identity of the automated de novo method is 86.3%.展开更多
