Analytically normal ring

An *analytically normal ring* is a concept that arises in the study of commutative algebra and algebraic geometry, particularly in connection with the behavior of rings of functions. The formal definition typically pertains to rings of functions that arise from algebraic varieties or schemes. A ring \( R \) is said to be **analytically normal** if the following holds: 1. **Integral Closure**: The ring \( R \) is integrally closed in its field of fractions.
