The question of reversibility was discussed in the paper title d ``On the deformation chirality of real cubic fourfolds'' by Finashin and Kharlamov. For $n=1$\, the case of plane curves\, and $d\\leq 5$ odd\, it is known that all smooth curves of degree $d$ are reversible. Our goal in this talk is to present an obstruction for reversibility of odd degree cu rves and use it in particular to demonstrate that there exist irreversible curves in $\\mathbb{RP}^2$ for all odd degrees $d\\geq 7$. This talk is b ased on joint work in progress with Ferit Öztürk.\n LOCATION:https://researchseminars.org/talk/OBAGS/54/ END:VEVENT END:VCALENDAR
