摘要: We study an invariant of plane algebraic curves with several components. Such invariant, called here a characterisitic variety, is collection subtori in the group characters fundamental complement to curve. This generalization one variable Alexander polynomial. The paper discusses basic properties varieties and their calculation terms position singularities curve plane.
