Having talked a bit about GR (general relativity) and the SM (standard model), lets talk a bit about QM (quantum mechanics). Without any doubt, GR,SM and QM are three extremely successful pillars of modern fundamental physics. Their track record with experiments is monumental (*). We have played with simple games …
Given a finite abstract simplicial complex G, there are two amazing matrices which are two sides of a coin. Both matrices are symmetric n x n matrices if G has n elements. The Dirac matrix D =d+d* is defined by the exterior derivative d(x,y) = sign(x,y) if y is incident …
We write a bit more about four papers which are relevant for the Fusion inequality on the Betti numbers of an open and closed pair in a simplicial complex.
