On an open subset in complex numbers

Suppose UC is an open subset. The sheaf of holomorphic functions on U is a sheaf of C-algebras defined as follows:

  • For every open subset VU, the algebra is the C-algebra of holomorphic functions on V
  • The restriction maps are simply function restriction
