A comment on “α-stability and α-synchronization for fractional-order neural networks”

In this paper, we point out that an inequality in the paper [J. Yu, C. Hu, H. Jiang, α-stability and α-synchronization for fractional-order neural networks, Neural Networks 35 (2012) 82-87] is not correct. The main theorems in this paper are not valid, since they are proved by this inequality.
