Nonlinear Self‐Adjoint Classification of a Burgers‐KdV Family of Equations
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 The concepts of strictly, quasi, weak, and nonlinearly self‐adjoint differential equations are revisited. A nonlinear self‐adjoint classification of a class of equations with second and third order is carried out.

Comparison of Different Approaches to Construct First Integrals for Ordinary Differential Equations
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 Different approaches to construct first integrals for ordinary differential equations and systems of ordinary differential equations are studied here. These approaches can be grouped into three categories: direct methods, Lagrangian or partial Lagrangian formulations, and characteristic (multipliers) approaches.

Cyclically Deformed Defects and Topological Mass Constraints
Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013 A systematic procedure for obtaining defect structures through cyclic deformation chains is introduced and explored in detail. The procedure outlines a set of rules for analytically constructing constraint equations that involve the finite localized energy of cyclically generated defects.

Gravity with Extra Dimensions and Dark Matter Interpretation: A Straightforward Approach
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 Any connection between dark matter and extra dimensions can be cognizably evinced from the associated effective energy‐momentum tensor. In order to investigate and test such relationship, a higher dimensional spacetime endowed with a factorizable general metric is regarded to derive a general expression for the stress tensor—from the Einstein‐Hilbert ...
