The Picard horn, also known as a Picard trumpet or Picard cone, is a type of mathematical object that arises in the study of topology and algebraic geometry. More specifically, it is a geometric structure that can be formed as a cone over a certain topological space, often related to the concept of a 'horn' in three-dimensional space.
