Abstract
Let an algebraic curve f have a singular point of type Aμ or Dμ. Let \({\tilde f}\) be the curve obtained by smoothing the singular point of f. In this paper, local maximal meanders appearing under an M-smoothing in a neighborhood of the singular point are studied. A local maximal meander means that the number of real points of the intersection of \({\tilde f}\) with a coordinate axis in the neighborhood is maximal and the points belong to one of the components of \({\tilde f}\). An M-smoothing means that the number of components of \({\tilde f}\) which appear in the neighborhood under the smoothing is also maximal. Bibliography: 9 titles.
