A perverse sheaf is a concept from algebraic geometry and sheaf theory, particularly in the context of the theory of derived categories and the study of singularities. It is a specific kind of sheaf that has been equipped with additional structure that allows for a refined understanding of the topology of spaces, particularly within the framework of non-abelian derived categories.
