Could you please elaborate on the concept of an affine scheme in the realm of algebraic geometry? How does it differ from other schemes, and what are its defining characteristics? Furthermore, could you provide an example or two to illustrate its application and significance within the broader context of mathematics and cryptography?

An affine scheme, in the realm of algebraic geometry, stands as the foundational object tied to a commutative ring. It encapsulates the essence of algebraic structures, providing a geometric interpretation to abstract algebraic concepts.

The cornerstone of an affine scheme lies in its points, which are intimately linked to the prime ideals of the underlying ring. Each prime ideal corresponds to a unique point, reflecting the deep connection between algebraic and geometric entities.

Further delving into the structure, the closed points of an affine scheme correspond precisely to the maximal ideals of the ring. These maximal ideals serve as the endpoints of the geometric interpretation, marking the termination of certain geometric paths.

The coordinate ring of an affine scheme plays a pivotal role, being none other than the ring itself. This self-reference underscores the inherent unity between the algebraic and geometric aspects of the affine scheme.

When considering open subsets of an affine scheme, their coordinate rings take on a specific form. These rings are constructed as fractions of the original ring, reflecting the more nuanced algebraic structures present in the open subsets.
