Discriminant, vertex and general type of a family of polynomials
Wallace Sousa
In this paper we give a formal expression to the limits of dual plane curves by using the method introduced by Katz. As an application, we give a formula to compute the vertices of…

Limits of dual curves via foliations
Eduardo Esteves, Nivaldo Medeiros, Wallace Sousa
We develop a method to compute limits of dual plane curves in Zeuthen families of any kind. More precisely, we compute the limit 0-cycle of the ramification scheme of a general lin…
