Sheaves

Sheaves

Sheaves are a mathematical concept used in various branches of mathematics, including algebraic geometry, complex analysis, and topology. In simple terms, a sheaf is a tool for systematically tracking local data attached to the open sets of a topological space. Sheaves help in understanding how local information can be glued together to obtain global information on the space. They are particularly useful in studying functions, differential forms, and cohomology theories.
