DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OBAGS/46/">R
 eal line arrangements and vanishing cycles</a>\nby Ichiro Shimada (Hiroshi
 ma) as part of ODTU-Bilkent Algebraic Geometry Seminars\n\n\nAbstract\nWe 
 investigate the topology of a double cover of a complex affine plane branc
 hing along a nodal real line arrangement.We define certain topological 2-c
 ycles in the double plane using the real structure of the arrangement.Thes
 e cycles resemble vanishing cycles of Lefschetz.We then  calculate their i
 ntersection numbers.\n
