چکیده

In this article we have showed that a gradient $\rho$-Einstein soliton with vector field of bounded norm and satisfying some other conditions is isometric to the Euclidean sphere. Later, proved non-trivial complete finite weighted Dirichlet integral certain restriction on Ricci curvature must be constant scalar steady flat. Finally, non-shrinking or non-expanding traceless possessing steady.

Solitons for nearly integrable bright spinor Bose-Einstein condensate

‎Using the explicit forms of eigenstates for linearized operator related to a matrix version of Nonlinear Schrödinger equation‎, ‎soliton perturbation theory is developed for the $F=1$ bright spinor Bose-Einstein condensates‎. ‎A small disturbance of the integrability condition can be considered as a small correction to the integrable equation‎. ‎By choosing appropriate perturbation‎, ‎the soli...

Solitons in Bose–Einstein condensates

The Gross–Pitaevskii equation (GPE) describing the evolution of the Bose–Einstein condensate (BEC) order parameter for weakly interacting bosons supports dark solitons for repulsive interactions and bright solitons for attractive interactions. After a brief introduction to BEC and a general review of GPE solitons, we present our results on solitons that arise in the BEC of hard-core bosons, whi...

Some Characterizations of Domination

We show that a cocycle has a dominated splitting if and only if there is a uniform exponential gap between singular values of its iterates. Then we consider sets Σ in GL(d, R) with the property that any cocycle with values in Σ has a dominated splitting. We characterize these sets in terms of existence of invariant multicones, thus extending a 2-dimensional result by Avila, Bochi, and Yoccoz. W...

SOME CHARACTERIZATIONS OF HYPER MV -ALGEBRAS

In this paper we characterize hyper MV -algebras in which 0 or1 are scalar elements . We prove that any nite hyper MV -algebra that 0is a scaler element in it, is an MV -algebra. Finally we characterize hyperMV -algebras of order 2 and order 3.

Bright Solitons in Bose-Einstein Condensates

It is a well-known fact that the interplay of nonlinearity and dispersion leads to the appearance of localized wavepackets moving without distortion. When the interaction between atoms is attractive (resp. repulsive), bright (resp. dark) solitons can be generated in BEC. Note that the term soliton is usually reserved to the localized solution of an integrable system [1]. Elastic scattering is a...
