Alex, D.2016-02-082016-02-082010http://hdl.handle.net/11693/22289We develop a geometric approach to the study of plane sextics with a triple singular point. As an application, we give an explicit geometric description of all irreducible maximal sextics with a type E7 singular point and compute their fundamental groups. All groups found are finite; one of them is nonabelian.EnglishArticle10.2140/gt.2010.14.3931364-0380
