One of its key motivations arises from Iitaka’s program in the 1970s\, which aimed to classify open varieties $U$.The approach involves compactifying $U$ into a projective variety $X$ by adding a boundary divisor $D$\, and then study ing the geometry of $U$ through the pair $(X\,D)$. Over time\, the theory of pairs has evolved significantly and has become a cornerstone of biratio nal geometry. After reviewing some historical developments in the theory o f pairs (including the concept of hyperbolicity for pairs)\, we turn our a ttention to Calabi-Yau pairs. In particular\, we present a framework\, dev eloped in collaboration with Alessio Corti and Alex Massarenti\, which all ows one to explicitly describe the birational geometry of Calabi-Yau pairs .\n\nOnline access: Zoom click here\n\nhttps://impa-br.zoom.us/j/821582572 29?pwd=gR6jcNMNUMDOaUgIlSUWhhaWPJG5NQ.1\n\nReunion ID : 821 5825 7229 PIN : 117619\n\nYouTube: click here\n\nLecture by Carolina Araujo (IMPA)\n\nP.
