Invariants of third‐order ordinary differential equations y′′′=f(x,y,y′,y′′) via point transformations
(
John Wiley and Sons Ltd
, 2016 , Article)
A new systematic method to find the relative invariant differentiation operators is developed. We incorporate this new approach with Lie's infinitesimal method to study the general class y′′′ = f(x, y, y′, y′′) under general ...
Higher order self-adjoint operators with polynomial coefficients
(
Texas State University - San Marcos
, 2017 , Article)
We study algebraic and analytic aspects of self-adjoint operators of order four or higher with polynomial coefficients. As a consequence, a systematic way of constructing such operators is given. The procedure is applied ...
Stagnation point flow study with water based nanoparticles aggregation over a stretching sheet: numerical solution
(
American Scientific Publishers
, 2016 , Article)
Intention of the current study is to examined the two dimensional stagnation point flow of waterbased nanofluid towards a stretching sheet. To simplify the problem similarity transformations are smearing on basic boundary ...
Embodied water for urban economy: A three-scale input-output analysis for Beijing 2010
(
Elsevier
, 2015 , Article)
The scheme of a three-scale input-output analysis is presented in this study to investigate the water use profile of the urban economy in Beijing. Defined as total water including direct and indirect water, embodied water ...
Invariant characterization of third-order ordinary differential equations u''=f(x,u,u',u) with five-dimensional point symmetry group
(
Elsevier B.V.
, 2019 , Article)
The Cartan equivalence method is applied to provide an invariant characterization of the third-order ordinary differential equation u''=f(x,u,u',u') which admits a five-dimensional point symmetry Lie algebra. The invariant ...
Classification of the Lie and Noether point symmetries for the Wave and the Klein–Gordon equations in pp-wave spacetimes
(
Elsevier B.V.
, 2018 , Article)
A complete classification of the Lie and Noether point symmetries for the Klein–Gordon and the wave equation in pp-wave spacetimes is obtained. The classification analysis is carried out by reducing the problem of the ...
Effect of Lorentz forces on forced-convection nanofluid flow over a stretched surface
(
Elsevier B.V.
, 2016 , Article)
Magnetic nanofluid hydrothermal analysis over a plate is studied that includes consideration of thermal radiation. The Runge-Kutta (RK4) method is utilized to get solution of ODEs which are obtained from similarity solution. ...
