The plural of acnode; multiple isolated singular points on algebraic curves where the curves touch themselves without crossing.
Direct plural of 'acnode,' following English pluralization rules. The mathematical concept originated in 18th-century algebraic geometry when mathematicians classified singular points on curves.
When you study complex algebraic curves in higher mathematics, you'll encounter acnodes alongside cusps and nodes—they're all different ways a curve can 'misbehave' at certain points, which tells us deep things about the curve's structure!
