Diverse solitary wave solutions of fractional order Hirota-Satsuma coupled KdV system using two expansion methods

open access: yesAlexandria Engineering Journal, 2023
The generalized Hirota-Satsuma coupled KdV system with fractional-order derivative plays a significant role to simulate the interaction of nearby identical-weight particles in a crystal lattice structure, two long waves interaction with different ...

Eigenstructure of the equilateral triangle. Part III. The Robin problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 16, Page 807-825, 2004., 2004
Lamé′s formulas for the eigenvalues and eigenfunctions of the Laplacian on an equilateral triangle under Dirichlet and Neumann boundary conditions are herein extended to the Robin boundary condition. They are shown to form a complete orthonormal system. Various properties of the spectrum and modal functions are explored.

Bäcklund transformations for several cases of a type of generalized KdV equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 63, Page 3369-3377, 2004., 2004
An alternate generalized Korteweg‐de Vries system is studied here. A procedure for generating solutions is given. A theorem is presented, which is subsequently applied to this equation to obtain a type of Bäcklund transformation for several specific cases of the power of the derivative term appearing in the equation. In the process, several interesting,

An approximate analytic solution of a particular boundary value problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 8, Page 513-520, 2001., 2001
This note is concerned with the three‐dimensional quasi‐steady‐state heat conduction equation subject to certain boundary conditions in the whole x′y′‐plane and finite in z′‐direction. This type of boundary value problem arises in laser welding process. The solution to this problem can be represented by an integral using Fourier analysis. This integral

Some properties of the Feynman‐Kac functional

open access: yesInternational Journal of Stochastic Analysis, Volume 8, Issue 1, Page 1-10, 1995., 1994
The Feynman‐Kac formula and its connections with classical analysis were initiated in the now celebrated paper [6] of M. Kac. It soon became obvious that the formula provides a powerful tool for solving partial differential equations by running the Brownian motion process. K.L. Chung and K.M.

Social Stratification within a Protohistoric Plankhouse of the Pacific Northwest Coast: Use-wear and Spatial Distribution Analysis of Chipped Lithic Artifacts

open access: yes, 1996
The spatial distribution of chipped lithic artifacts excavated at site 35C05, a Chinookan plankhouse of the protohistoric period, was observed to test the hypothesis that a gradient of material culture -- reflecting social status -- should be evident ...

Note on a boundary value problem of Poisson's equation

open access: yes, 2013
This note shows that for a BVP of Poisson’s equation withQ m(u, v) as its source function, a direct evaluation of some integrals yields the same exact results as obtained by similarity analysis ...
