4. Reductions and conservation laws for BBM and modified BBM equations

Author

Khorshidi Maryam, Nadjafikhah Mehdi, Jafari Hossein, and Al Qurashi Maysaa

Subjects
lie symmetries, group-invariant solutions, optimal system of lie sub-algebras, conservation laws, bbm and mbbm equations, 70h33, 34k17, 70g65, Mathematics, QA1-939
Abstract

In this paper, the classical Lie theory is applied to study the Benjamin-Bona-Mahony (BBM) and modified Benjamin-Bona-Mahony equations (MBBM) to obtain their symmetries, invariant solutions, symmetry reductions and differential invariants. By observation of the the adjoint representation of Mentioned symmetry groups on their Lie algebras, we find the primary classification (optimal system) of their group-invariant solutions which provides new exact solutions to BBM and MBBM equations. Finally, conservation laws of the BBM and MBBM equations are presented. Some aspects of their symmetry properties are given too.

6. Fractional derivative generalization of Noether’s theorem

Author

Khorshidi Maryam, Nadjafikhah Mehdi, and Jafari Hossein

Subjects
fractional derivatives, symmetry, fractional variational calculus, fractional euler–lagrange equations, conservation laws, noether’s theorem, Mathematics, QA1-939
Abstract

The symmetry of the Bagley–Torvik equation is investigated by using the Lie group analysis method. The Bagley–Torvik equation in the sense of the Riemann–Liouville derivatives is considered. Then we prove a Noetherlike theorem for fractional Lagrangian densities with the Riemann-Liouville fractional derivative and few examples are presented as an application of the theory.

9. Lie symmetry analysis and conservation laws of dissipative nonlinear evolution equations with ellipticity

Author

Nadjafikhah, Mehdi and Khorshidi, Maryam

Abstract

Lie symmetry group theory is one of the most important methods in analysis of differential equations. Such Lie groups are invertible point transformations which result in the movement of dependent and independent variables of the differential equations. Constructing the solutions of nonlinear PDEs, mapping them to another solution by linear transformations, symmetry reductions and conservation laws are several principal applications of this theory.

10. Mother load: A TIME STUDY HELPS LOWER CLINIC WAIT TIMES, KEEPING PATIENTS EXPECTANT AND LESS FRUSTRATED.

Author

Stucki, Zachary, Khorshidi, Maryam, Jones, Justin, Bovaird, Peter, Scaffidi, Myke, and Jin-Chang Zhou

Abstract

The article offers information related to the methods for keeping Patients expectant and less frustrated in the clinical centers. Topics discussed include create a process diagram and identify potential points of improvement; concentrated around the ultrasound exam or a visit with a maternal-fetal medicine (MFM) specialist; and report writing can be assigned to sonographers, allowing scanning to increase their capacity.

15. Fixed Point Results for Generalized ℱ-Contractions in Modular b-Metric Spaces with Applications.

Author

Parvaneh, Vahid, Hussain, Nawab, Khorshidi, Maryam, Mlaiki, Nabil, and Aydi, Hassen

Subjects
SPACE, METRIC spaces
Abstract

The aim of this paper is to generalize the F -contractive condition in the framework of α − ν -complete modular b-metric spaces. Some results in ordered modular b-metric spaces are also presented. Moreover, an illustrative example and some related applications are presented to support the obtained results. [ABSTRACT FROM AUTHOR]
