In this article, we delve into the exponential stability of uncertainty systems characterized by stochastic differential equations driven by G-Brownian motion, where coefficient uncertainty exists. To stabilize the system when it is unstable, we cons

With the notion of independent identically distributed (i.i.d.) random variables under sublinear expectations initiated by Peng, a strong law of large numbers for weighted sums of i.i.d. random variables under capacities induced by sublinear expectat

In this paper, we propose a new stochastic epidemic model as follows dY(t)=G(Y(t))d⟨B⟩(t)+H(Y(t))dB(t), where G(Y)=(R1−1)R2Y+(R3R4−R5)Y(1−Y),H(Y)=R4R6Y(1−Y),andB(t)istheG−Brownianmotion. The model ...

A stochastic Lotka–Volterra model disturbed by G-Brownian motion (G-LVM for short) in the framework of non-linear expectation is proposed in this paper. This model takes into account the uncertaint...

Estimation of high-dimensional covariance structure is an interesting topic in statistics. Motivated by the work of Lin et al. [9], in this paper, the quadratic loss function is proposed to measure the discrepancy between a real covariance matrix and
