acnode
An acnode is a type of singularity that can occur in algebraic curves. It is characterized by being an isolated point on the curve where the curve has no tangent. In simpler terms, imagine a smooth curve that suddenly stops and has a single, isolated point without any direction. This isolated point is the acnode.
Mathematically, an acnode can be identified by analyzing the local behavior of the algebraic curve near that
Acnodes are distinct from other types of singularities like nodes (where the curve crosses itself, forming
