Degtyarev, A.2015-07-282015-07-2820140218-2165http://hdl.handle.net/11693/12581We derive explicit defining equations for a number of irreducible maximizing plane sextics with double singular points only. For most real curves, we also compute the fundamental group of the complement; all groups found are abelian, which suffices to complete the computation of the groups of all non-maximizing irreducible sextics. As a by-product, examples of Zariski pairs in the strongest possible sense are constructed. © 2014 World Scientific Publishing Company.EnglishBertini InvolutionElliptic PencilFundamental GroupPlane SexticZariski PairArticle10.1142/S021821651450028X Alex Degtyarev0218-2165
