Computation and observation of novel interaction based on the mixed solutions to a generalized Bogoyavlensky–Konopelchenko equation

Partial Differential Equations in Applied Mathematics, 2022
A generalized Bogoyavlensky–Konopelchenko equation is introduced by using p-generalized bilinear differential operators. The lump solutions, one-lump-one-kink and one-lump-two-kink solutions are derived with symbolic computations.

New Lump-like Structures in Scalar-field Models

, 2008
In this work we investigate lump-like solutions in models described by a single real scalar field. We start considering non-topological solutions with the usual lump-like form, and then we study other models, where the bell-shape profile may have varying

One lump or two? [PDF]

, 2009
We investigate methods for modelling metabolism within populations of cells. Typically one represents the interaction of a cloned population of cells with their environment as though it were one large cell. The question is as to whether any dynamics are

A Rare Case of Ovarian Dysgerminoma with Torsion in Pregnancy [PDF]

Journal of Clinical and Diagnostic Research
Early identification of the clinical and imaging characteristics of ovarian dysgerminoma is crucial for prompt care of this rare malignant germ cell tumour, which primarily affects young women and adolescents.

A tachyon lump in closed string field theory

, 2008
We find a codimension one lump solution of closed bosonic string field theory. We consider vertices up to quartic order and include in the string field the tachyon, the ghost dilaton, and a metric fluctuation. While the tachyon profile clearly is that of

Boundary and Midpoint Behaviors of Lump Solutions in Vacuum String Field Theory [PDF]

, 2005
We discuss various issues concerning the behaviors near the boundary (\sigma=0,\pi) and the midpoint (\sigma=\pi/2) of the open string coordinate X(\sigma) and its conjugate momentum P(\sigma)=-i\delta/\delta X(\sigma) acting on the matter projectors of ...

Correspondence between Skyrmions in 2+1 and 3+1 Dimensions

, 2013
A lump (2D Skyrmion) can be constructed as a sine-Gordon kink (1D Skyrmion) inside a domain wall in the massive O(3) sigma model. In this paper, we discuss relations between Skyrmions in 2+1 and 3+1 dimensions.

Lump, lump-stripe, and breather wave solutions to the (2 + 1)-dimensional Sawada-Kotera equation in fluid mechanics

Heliyon, 2021
The present study investigates the lump, one-stripe, lump-stripe, and breather wave solutions to the (2+1)-dimensional Sawada-Kotera equation using the Hirota bilinear method.
