In algebraic geometry, the theorem on formal functions states the following: The theorem is used to deduce some other important theorems: Stein factorization and a version of Zariski's main theorem that says that a proper birational morphism into a normal variety is an isomorphism.

Tropical geometry
In mathematics, tropical geometry is the study of polynomials and their geometric properties when addition is replaced with minimization and multiplication is replaced with ordinary addition: So for example, the classical polynomial x^3 + 2xy + y^4 would become \min\.

Valuation ring
In abstract algebra, a valuation ring is an integral domain D such that for every non-zero element x of its field of fractions F, at least one of x or x−1 belongs to D. Given a field F, if D is a subring of F such that either x or x−1 belongs to D for every nonzero x in F, then D is said to be a valuation ring for the field F or a place of F.

Vector bundle
In mathematics, a vector bundle is a topological construction that makes precise the idea of a family of vector spaces parameterized by another space X (for example X could be a topological space, a manifold, or an algebraic variety): to every point x of the space X we associate (or "attach") a vector space V(x) in such a way that these vector spaces fit together to form another space of the same kind as X (e.g.

Virtual fundamental class
In mathematics, specifically enumerative geometry, the virtual fundamental class ^\text_ of a space X is a replacement of the classical fundamental class \in A^*(X) in its Chow ring which has better behavior with respect to the enumerative problems being considered.

Weil reciprocity law
In mathematics, the Weil reciprocity law is a result of André Weil holding in the function field K(C) of an algebraic curve C over an algebraically closed field K. Given functions f and g in K(C), i.e. rational functions on C, then where the notation has this meaning: (h) is the divisor of the function h, or in other words the formal sum of its zeroes and poles counted with multiplicity; and a function applied to a formal sum means the product (with multiplicities, poles counting as a negative multiplicity) of the values of the function at the points of the divisor.

Yoneda lemma
In mathematics, the Yoneda lemma is a fundamental result in category theory.

Zariski tangent space
In algebraic geometry, the Zariski tangent space is a construction that defines a tangent space at a point P on an algebraic variety V (and more generally). Glossary of algebraic geometry and Zariski tangent space are algebraic geometry.

In algebraic geometry and commutative algebra, the Zariski topology is a topology defined on geometric objects called varieties. Glossary of algebraic geometry and Zariski topology are scheme theory.

Zariski's main theorem
In algebraic geometry, Zariski's main theorem, proved by, is a statement about the structure of birational morphisms stating roughly that there is only one branch at any normal point of a variety.

Zariski–Riemann space
In algebraic geometry, a Zariski–Riemann space or Zariski space of a subring k of a field K is a locally ringed space whose points are valuation rings containing k and contained in K. They generalize the Riemann surface of a complex curve. Glossary of algebraic geometry and Zariski–Riemann space are algebraic geometry.
