T hey are fibrations whose general fibres are abelian varieties that are Lag rangian with respect to the symplectic form. Markushevich and Tikhomirov d escribed the first example whose fibres are Prym varieties\, and their con struction was further developed by Arbarello\, Ferretti\, and Sacca and by Matteini to yield more examples. In this talk we describe the general fra mework\, and consider a new example. We describe its singularities and sho w that it is a 'primitive' symplectic variety. We also construct the dual fibration\, using ideas of Menet. This is joint work with Chen Shen.\n LOCATION:https://researchseminars.org/talk/Geolis/35/ END:VEVENT END:VCALENDAR
