On warped product bi-slant submanifolds of Kenmotsu manifolds

Siraj Uddin, Ion Mihai, Adela Mihai

Chen (2001) initiated the study of CR-warped product submanifolds in Kaehler manifolds and established a general inequality between an intrinsic invariant (the warping function…

On Hilbert class field tower for some quartic number fields

Abdelmalek Azizi, Mohamed Talbi, Mohammed Talbi

We determine the Hilbert 2-class field tower for some quartic number fields k whose 2-class group Ck,2 is isomorphic to ℤ/2ℤ×ℤ/2ℤ.

A Method of approximation for a zero of the sum of maximally monotone mappings in Hilbert spaces

Getahun Bekele Wega, Habtu Zegeye

Our purpose of this study is to construct an algorithm for finding a zero of the sum of two maximally monotone mappings in Hilbert spaces and discus its convergence. The…

Warped product pointwise semi-slant submanifolds of cosymplectic space forms and their applications

Lamia Saeed Alqahtani

In this paper some characterizations for the existence of warped product pointwise semi-slant submanifolds of cosymplectic space forms are obtained. Moreover, a sharp estimate for…

Note on a W1,∞(L2)-error estimate of a nonlinear finite volume scheme for a semi-linear heat equation

Ahmed Berkane, Abdallah Bradji

We consider, as discretization in space, the nonconforming mesh developed in SUSHI (Scheme Using Stabilization and Hybrid Interfaces) developed in Eymard et al. (2010) for a…
