Discrete valuation

In mathematics, a discrete valuation is an integer valuation on a field K; that is, a function: satisfying the conditions: for all . Note that often the trivial valuation which takes on only the values is explicitly excluded. A field with a non-trivial discrete valuation is called a discrete valuation field. (Wikipedia).

DISCRETE Random Variables: Finite and Infinite Distributions (9-2)

A Discrete Random Variable is any outcome of a statistical experiment that takes on discrete (i.e., separate and distinct) numerical values. Discrete outcomes: all potential outcomes numerical values are integers (i.e., whole numbers). They cannot be negative. Using an example of tests in

Schemes 22: Valuation rings

This lecture is part of an online algebraic geometry course on schemes, based on chapter II of "Algebraic geometry" by Hartshorne.. We review valuation rings. We give a few examples of discrete and non-discrete valuation rings, and give a brief sketch of how non-discrete valuation rings us

Schemes 25: Proper morphisms and valuations

This lecture is part of an online algebraic geometry course on schemes, based on chapter II of "Algebraic geometry" by Hartshorne. We describe how to test a morphism for being proper using discrete valuation rings, and use this to show that projective morphisms are proper.
