Neutrino Mixing Matrix in Terms of Neutrino Mass Matrix and Its Frobenius Covariants

An explicit expression is derived for the mixing matrix of Majorana neutrinos in terms of the mass matrix and its Frobenius covariants. Illustrative scenarios are taken as examples where the suggested formula is used to obt...

Mass Lumping Methods for the SemiLoof Shell Element

A particular attention is focused on the mass matrix diagonalization of the semi-loof shell element. Mass matrix diagonalization in terms of a finite element method (FEM) is essential for an effective deployment of...
