A Short Lecture on Divergences
Alejandro Rivero
We present some clues to the study of the renormalization group, at graduate level, as well as some bibliographical pointers to classical resources. Just the kind of things one had…
Around Poincare duality, in discrete spaces
Alejandro Rivero
We walk out the landscape of K-theoretic Poincare Duality for finite algebras. It paves the way to get continuum Dirac operators from discrete noncommutative manifolds.
Lessons from Numerical Analysis
Alejandro Rivero
It is reviewed how Renormalization Group, species doubling and CKM mixing are known to appear in numerical analysis: Butcher group, parasitic solutions and higher order methods
Some conjectures looking for a NCG theory
Alejandro Rivero
It is pointed out that ambiguities in the regularization of actions with second derivatives seem to happen with the same multiplicity that the standard model of elementary particle…
