We are concerned with the three-component generalized Gross-Pitaevskii Equations (GGPE) in the spinor Bose-Einstein condensates with trapping potentials. Under certain conditions on trapping potentials and parameters, we establish the existence and uniqueness of corresponding standing wave solutions with behaviors tending to zero at infinity. The same issues for the corresponding Dirichlet boundary value problems on the ball centered at the origin are also concluded. Additionally, we provide a classification of various types of solutions to radially symmetric situations.
In this paper, we prove the existence and uniqueness of solitary wave solutions of time-dependent nonlinear Schrödinger equations with behaviors tending to zero at infinity under certain conditions on trapping potentials and parameters. In addition, we provide the same issues for the Dirichlet boundary value problems on the ball centered at the origin. A classification of solutions for radial case is also established. Particularly, for constant trapping potentials, we conclude that there is at most one radial ground state under certain conditions on parameters.

AbstractIn this paper, we consider a nonlinear elliptic system which is an extension of the single equation derived by investigating the stationary states of the nonlinear Schrödinger equation.

Neuromuscular impairments in Parkinson's disease (PD) alter the mechanics and control of the body, leading to an increased risk of falling during more challenging functional tasks such as obstacle-crossing. However, little is known about these changes. The current study aimed to bridge the gap by quantifying the motion of the body's center of mass (COM) relative to the center of pressure (COP) in terms of COM-COP inclination angles (IA) and their rate of change (RCIA) in fifteen older adults with mild PD and fifteen healthy controls when crossing obstacles of heights of 10, 20 and 30% leg length. There were no between-group differences for either the leading or trailing toe clearances (p > 0.05). With the unaffected limb leading, the PD subjects significantly increased the crossing sagittal and frontal IA, crossing sagittal RCIA, the peak RCIA, and average sagittal and frontal RCIAs during double-limb support for all obstacle heights when compared to those with the affected limb leading and those of the Controls (p < 0.05). The poor balance control in the mediolateral direction during obstacle-crossing in PD indicated an increased risk of falling. The differences in the crossing patterns between leading with the affected or unaffected limb suggest that patients with PD should lead with the affected limb when crossing obstacles. The current findings suggest that early dynamic balance training is important in the management of patients with PD.
In this paper, we prove the uniqueness of topological solutions for the self-dual Maxwell–Chern–Simons O(3) sigma model under the conditions on Chern–Simons coupling parameter and the charge of electron.

Convexity of spaces plays a very important role in non-linear analysis theory , variational inequality theory , optimal theory and so on .In all these cases of theoretical and applied studies , the dependence on the con-vexity of spaces is presumed .However , a lot of spaces do not possess the convex property from the viewpoint of the usual linear structure .Because of this , it has become recent interest to establish generalized convexity on spaces without linear structure and to generalize the continuity selection theorem , the fixed point theorem and some other important results , to generalized convex spaces .Here we make full use of the H0-condition of T-convex space and classical analysis method , to prove KKM lemma on T-convex space without linear structure .Finally , we study two applications of this lemma on T-convex space .One is the fixed point theorem and the other is the existence theorem for the solution of Ky Fan inequality without quasi-T-concavity on T-convex spaces .
