Thermodynamics and phase transitions of nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory
De-Cheng Zou, Xu Yang, Meng-Yun Lai +2
We investigate the thermodynamic properties of static nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory with polynomial coupling functions. Based on the sca…
Extinction behaviour for mutually enhancing continuous-state population dynamics
Jie Xiong, Xu Yang, Xiaowen Zhou
In this paper, we study a two-dimensional process arising as the unique nonnegative solution to a system of two stochastic differential equations (SDEs) with mutually enhancing two…
Existence of nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory with polynomial couplings
De-Cheng Zou, Xu Yang, Meng-Yun Lai +5
Nonlinearly scalarized black holes are investigated in Einstein-scalar-Gauss-Bonnet (EsGB) theory with polynomial coupling functions satisfying , where $ζ'(υ
Extinction behaviour for competing continuous-state population dynamics
Jie Xiong, Xu Yang, Xiaowen Zhou
We consider a system of two stochastic differential equations (SDEs) with competing two-way interactions driven by Brownian motions and spectrally positive -stable random measu…
Extinction, explosion and contraction for time-inhomogeneous SDEs with jumps
Shukai Chen, Xu Yang, Xiaowen Zhou
For a class of time-inhomogeneous SDEs with jumps, we establish criteria for the existence and uniqueness of the nonnegative solutions, and examine the extinction, the explosion to…
