In algebraic geometry and commutative algebra, a Weierstrass ring is a type of local ring that can be used to study singularities of algebraic varieties. More specifically, it is a particular kind of ring that arises in the context of the Weierstrass preparation theorem. A Weierstrass ring is defined as follows: 1. **Local Ring**: It is a local ring, which means it has a unique maximal ideal.
