A regularity criterion in multiplier spaces to Navier-Stokes equations via the gradient of one velocity component
Ahmad M. Alghamdi, Sadek Gala, Maria Alessandra Ragusa
In this paper, we study regularity of weak solutions to the incompressible Navier-Stokes equations in . The main goal is to establish the regularity cri…
A regularity criterion of 3D incompressible MHD system with mixed pressure-velocity-magnetic field
Ahmad M. Alghamdi, Sadek Gala, Maria Alessandra Ragusa
This work focuses on the 3D incompressible magnetohydrodynamic (MHD) equations with mixed pressure-velocity-magnetic field in view of Lorentz spaces. Our main result shows the weak…
On normalized Laplacian eigenvalues of power graphs associated to finite cyclic groups
Bilal A. Rather, S. Pirzada, T. A. Chishti +1
For a simple connected graph of order , the normalized Laplacian is a square matrix of order , defined as $\mathcal{L}(G)= D(G)^{-\frac{1}{2}}L(G)D(G)^{-\frac{1}{2}…
A regularity criterion to the 3d Boussinesq equations
A. M. Alghamdi, I. Ben Omrane, S. Gala +1
The paper deals with the regularity criterion for the weak solutions to the 3D Boussinesq equations in terms of the partial derivatives in Besov spaces. It is proved that the weak…
On k(D)-blocks
Ahmad Alghamdi
The objective of this research paper is to study the relationship between a block of a finite group and a defect group of such block. We define a new notion which is called a stron…
Remarks on the tensor degree of finite groups
Ahmad M. A. Alghamdi, Francesco G. Russo
The present paper is a note on the tensor degree of finite groups, introduced recently in literature. This numerical invariant generalizes the commutativity degree through the noti…
A generalization of the probability that the commutator of two group elements is equal to a given element
Ahmad M. A. Alghamdi, Francesco G. Russo
The probability that the commutator of two group elements is equal to a given element has been introduced in literature few years ago. Several authors have investigated this notion…
