MATH Seminar: “Real Line Arrangements and Vanishing Cycles”, 3:40PM April 19 2024 (EN)

You are cordially invited to the ODTU-Bilkent Algebraic Geometry Seminar.

Speaker: Ichiro Shimada (Hiroshima University)

“Real line arrangements and vanishing cycles”

Abstract: We investigate the topology of a double cover of a complex affine plane branching along a nodal real line arrangement.We define certain topological 2-cycles in the double plane using the real structure of the arrangement.These cycles resemble vanishing cycles of Lefschetz.We then calculate their intersection numbers.
