Chains in evolution algebras
(ELSEVIER, 2021-08-01)In this work we approach three-dimensional evolution algebras from certain constructions performed on two-dimensional algebras. More precisely, we provide four different constructions producing three-dimensional evolution ... -
Fuzzy closure structures as formal concepts
(Elsevier, 2022-12-28)Galois connections seem to be ubiquitous in mathematics. They have been used to model solutions for both pure and application-oriented problems. Throughout the paper, the general framework is a complete fuzzy lattice over ... -
Lorentzian Metrics Null-Projectively Related to Semi-Riemannian Metrics
(Springer Nature, 2022-12-19)We say that a Lorentzian metric and a semi-Riemannian metric on the same manifold M are null-projectively related if every null geodesic of the Lorentzian metric is an unparametrized geodesic of the semi-Riemannian one. ...
