Neutrino mass and mixing, resonant leptogenesis and charged lepton flavor violation in a minimal inverse seesaw model with $S_{4}$ symmetry

V. V. Vien, Mayengbam Kishan Singh

We propose a minimal inverse seesaw model with $S_{4}$ symmetry for the Majorana neutrinos with only one real ( $m_{0}$ )-and two complex ( $I^\pm, I^^{2}$ ) parameters in neutrino sector which g…

A Riemannian gradient descent method for optimization on the indefinite Stiefel manifold

Dinh Van Tiep, Nguyen Thanh Son

We consider the optimization problem with a generally quadratic matrix constraint of the form $X^{T} A X = J$ , where $A$ is a given nonsingular, symmetric $n \times n$ matrix and $J$ is…

Cohen-Macaulayness of formal fibers and dimension of local cohomology modules

Tran Do Minh Chau

Let $(R, m)$ be a Noetherian local ring, $M$ a finitely generated $R$ -module of dimension $d$ . Set $a (M) := a_{0} (M) \dots a_{d - 1} (M)$ , whe…
