%0 Journal Article %T Generalized Zariski-van Kampen theorem and its application to Grassmannian dual varieties %A Ichiro Shimada %J Mathematics %D 2009 %I arXiv %X We formulate and prove a generalization of Zariski-van Kampen theorem on the topological fundamental groups of smooth complex algebraic varieties. As an application, we prove a hyperplane section theorem of Lefschetz-Zariski-van Kampen type for the fundamental groups of the complements to the Grassmannian dual varieties. %U http://arxiv.org/abs/0906.1074v1
