# User:Richard Pinch/Redlinks

From Citizendium

A list of redlinks I've created with the intention of filling in at some time:

- Universal property
- Tychonoff product theorem
- Paving dimension
- Matroid, Geometric lattice
- General topology or possibly Point-set topology
- Galois group, Galois extension
- Galois connection
- Finite set, Infinite set
- Bolzano-Weierstrass theorem
- Conductor of an elliptic curve

From Centre (mathematics):

- In triangle geometry
- The excentres, centres of the three circles internally tangent to one side and externally to the other two

From Chain (mathematics):

- A linearly ordered sequence of elements of a partial order
- An element of a group in a chain complex in homological algebra
- The chain rule for the derivative of function composition

From Talk:Series (mathematics):

- Series (analysis), the cumulative sum of a given sequence of terms. Special types include
- Dirichlet series
- Fourier series
- Power series (currently a redirect)
- Puiseux series

- Series (group theory), a chain of subgroups of a group. Special types include
- Series (lattice theory), a chain in a partially ordered set
- Time series in probability and statistics

From Distributivity:

- There are three closely connected examples where each of two operations distributes over the other:
- In set theory, intersection distributes over union and union distributes over intersection;
- In propositional logic, conjunction (logical and) distributes over disjunction (logical or) and disjunction distributes over conjunction;
- In a Boolean algebra, join distributes over meet and meet distributes over join.
