SUMMARY:Seminar Algebra and Geometry: Daniela Paiva (IMPA)
DESCRIPTION:The problem of determining which automorphisms of a projective 
 K3 surface S are induced by birational maps of an ambient space in which i
 t is embedded remains open. This is known as Gizatullin’s problem. In th
 is seminar\, I will provide a general background on the theory of K3 surfa
 ces and the birational geometry of Fano 3-folds\, and explain how the inte
 rplay between these areas can be exploited to address the problem. In part
 icular\, I will present a solution to Gizatullin’s problem in certain sp
 ecific cases. The results I will present are part of joint work with Carol
 ina Araujo\, Michela Artebani\, Alice Garbagnati\, Ana Quedo\, and Sokrati
 s Zikas.
