Theorems in algebraic topology | Algebraic K-theory

Basic theorems in algebraic K-theory

In mathematics, there are several theorems basic to algebraic K-theory. Throughout, for simplicity, we assume when an exact category is a subcategory of another exact category, we mean it is strictly full subcategory (i.e., isomorphism-closed.) (Wikipedia).

The Fundamental Theorem of Calculus | Algebraic Calculus One | Wild Egg

In this video we lay out the Fundamental Theorem of Calculus --from the point of view of the Algebraic Calculus. This key result, presented here for the very first time (!), shows how to generalize the Fundamental Formula of the Calculus which we presented a few videos ago, incorporating t

How to write an algebraic proof

šŸ‘‰ Learn how to write an algebraic proof. Algebraic proofs are used to help students understand how to write formal proofs where we have a statement and a reason. In the case of an algebraic proof the statement will be the operations used to solve an algebraic equation and the reason will

FIT2.3.1. Algebraic Numbers

Field Theory: We consider the property of algebraic in terms of finite degree, and we define algebraic numbers as those complex numbers that are algebraic over the rationals. Then we give an overview of algebraic numbers with examples.

Field Theory - Algebraically Closed Fields (part 2) - Lecture 10

In this video we should that algebraically closed fields exist and are unique. We assume that the direct limit construction works. The construction here depends on the axiom of choice.

A crash course in Algebraic Number Theory

A quick proof of the Prime Ideal Theorem (algebraic analog of the Prime Number Theorem) is presented. In algebraic number theory, the prime ideal theorem is the number field generalization of the prime number theorem. It provides an asymptotic formula for counting the number of prime idea

Fundamental Theorem of Algebra

In this video, I prove the Fundamental Theorem of Algebra, which says that any polynomial must have at least one complex root. The beauty of this proof is that it doesnā€™t use any algebra at all, but instead complex analysis, more specifically Liouvilleā€™s Theorem. Enjoy!
