This phenomena is known in literature as No ise Induced Order\, and was first observed in a model of the Belosouv-Zhab otinsky reaction and its existence was proven only recently by Galatolo-Mo nge-Nisoli. In the talk I will show how this phenomena is strictly connect ed with non-uniform hyperbolicity and the coexistence of regions of expans ion and contraction in phase space\; the result is attained through a resu lt on the continuity of the Lyapunov exponent of the stationary measure wi th respect to the size of the noise.\n LOCATION:https://researchseminars.org/talk/DinAmicI/11/ END:VEVENT END:VCALENDAR
