(That is the transition functions are now antiholomorphic). Then the product manifold ${\mathbb{C}}\times \bar{\mathbb{C}}$ has a sheaf of rings formed ${\mathbb{C}}[x]\otimes \mathbb{C}[\bar{y}]$ by tensoring the original two coordinate sheaves. Restricting along the diagonal $(x,\bar{x})$ gives the ${\mathbb{C}}[x,\bar{x}]$ | |
