Dimensionality-induced critical phase transition in stochastic Lotka-Volterra equation: From statistical averaging to systemic tipping point
Xiu-deng Zheng, Cong Li, Hui Zhang +3
By analyzing a stochastic Lotka-Volterra (LV) equation, we show that the underlying logic behind the diversity-stability debate in ecology can be framed as a dimensionality-induced…

The invariance and non-decreasing expectation of an evolutionary path characteristic under weak selection
Yun-Yun Yu, Cang Hui, Tian-Jiao Feng +4
Fisher's fundamental theorem of natural selection states that the rate of change in a population's mean fitness equals its additive genetic variance in fitness. This implies that m…
