• The word hysteresis means etymologically `to come behind'. It was introduced into the scientific vocabulary about 120 years ago by the Scottish physicist Alfred Ewing as follows ``when there are two quantities and , such that cyclic variations of cause cyclic variation of , then if the changes of lag behind those of , we may say that there is hysteresis in the relation of and '' 3 . ...
• ) Hysteresis occurs in many engineering, physical and economic systems. For example, in the ICT area hysteresis: ``stores'' information in dynamic memory; allows neural-networks to learn; affects the orbits of communication satellites via ferro-magnetic friction. The principal role of hysteresis in the post-Keinessian economics is splendidly highlighted in 2 . ...

The assumed nonlinearities are such that the area of the hysteresis loop vanishes as the forcing frequency tends to zero; in other words, there is no static hysteresis. ...
