A growing body of literature shows this. Papers the level fair price, are rather scarce. Based different concepts justice, two levels prices proposed: square equity mean prices. I run experiment which that both considered fairer than...

Abstract In this paper, we first consider the stability problem for a class of stochastic quaternion-valued neural networks with time-varying delays. Next, cannot explicitly decompose systems into equivalent real-valued systems; by using Lyapunov functional and analysis techniques, can obtain sufficient conditions mean-square exponential input-to-state networks. Our results are completely new. ...
