Lie group analysis, numerical and non-traveling wave solutions for the (2+1)-dimensional diffusion–advection equation with variable coefficients
收藏 引用
Chinese Physics B 2014年 第3期23卷 71-76页
作者: Vikas Kumar R.K.Gupta ram jiwari Department of Mathematics D.A.V.College Pundari School of Mathematics and Computer Applications Thapar University
In this paper, the variable-coefficient diffusion-advection (DA) equation, which arises in modeling various physical phenomena, is studied by the Lie symmetry approach. The similarity reductions are derived by deter... 详细信息

Chinese Physics B 2013年 第5期22卷 60-66页
作者: Vikas Kumar R. K. Gupta ram jiwari School of Mathematics and Computer Applications Thapar University
The Lie symmetry analysis is performed for the coupled short plus (CSP) equation. We derive the infinitesimals that admit the classical symmetry group. Five types arise depending on the nature of the Lie symmetry ge... 详细信息

Communications in Theoretical Physics 2013年 第8期60卷 175-182页
作者: Vikas Kumar R.K.Gupta ram jiwari School of Mathematics and Computer Applications Thapar UniversityPatiala147004PunjabIndia
In this paper, a variable-coefficient Benjarnin-Bona-Mahony-Burger (BBMB) equation arising as a math- ematical model of propagation of small-amplitude long waves in nonlinear dispersive media is investigated. The in... 详细信息
