摘要: In this paper, we study the intersection multiplicity of algebraic curves at a point both in R2 and in real projective plane P2. We introduce the fold point of curves and provide conditions for the relations between the intersection multiplicity of curves at a point and the folds of the point. 

关键词: Algebraic curves, intersection multiplicity, projective transformation, d-fold point

Abstract: In this paper, we study the intersection multiplicity of algebraic curves at a point both in R~2 and in real projective plane P~2. We introduce the fold point of curves and provide conditions for the relations between the intersection multiplicity of curves at a point and the folds of the point. 

Key words: Algebraic curves, intersection multiplicity, projective transformation, d-fold point
