Abstract:

On account of the fact that a fractional Brownian motion (fBm) with the Hurst parameter H ∈(0,1/2)∪(1/2,1) cannot follow the laws of the semimartingale and the Markov process, little work is presented about the T-stability for stochastic differential equations (SDEs) with fBm. Here, three results are obtained for the generalized Black-Scholes model (SDE) with H∈(1/3,1/2). Firstly, the sufficient conditions of the stochastical and asymptotical stability in the large for such equation are presented by the aid of the Lyapunov exponent. Secondly, the Euler-Maruyama (EM) numerical algorithm with a given step-size for such model is constructed. Lastly, by taking advantage of the stable average function, the sufficient conditions of the T-stability that originated from the EM algorithm are presented. All the results show that on the basis of the stability of such equation, the T-stable region produced by the EM algorithm can be found. Moreover, one numerical example is afforded to the main conclusions.
