Re-filtración y propiedades de regularidad de anillos multi-filtrados [PDF]
arXiv, 2013 Quantum bounded extensions of multifiltered algebras are defined, and they are endowed with a new multifiltration. The behavior of the associated multigraded rings is studied. A refiltering process allows to lift homological properties from the associated multigraded ring to the multifiltered ring.

sPad of Super Accuracy and Geometry in Old Babylon. -- sPad de Súper Exactitud y Geometría en la Antigua Babilonia [PDF]
arXiv, 2020 Recently it has been discovered that on a stone tablet over 3800 years old, the Plimpton-322 table, are carved the geometric relations that exist between the sides of 15 right triangles chosen in a very special way. Due to its property as a super accuracy calculation tool, in this work we have called it sPad by stone pad, and we have calculated its ...
