General Monogamy Relations for Multiqubit W-class States in terms of negativity and squared Rényi- entanglement
Yanying Liang, Xiufang Feng, Wei Chen
For multipartite entangled states, entanglement monogamy is an important property. We investigate the monogamy relations for multiqubit generalized W-class states. We present new a…

Existence of Positive Solution of a Class of Semi-linear Sub-elliptic Equation in the Entire Space
Zhu-Jun Zheng, Xiu-Fang Feng
In this paper, we study the following problem $$ \{{ll} Δ_{H^n} u-u+u^p=0 & in H^n u>0& in H^n u(x)\to 0 &ρ(x)\to\infty}. $$ where , Q is the homogeneous dim…
