A list of redlinks I've created with the intention of filling in at some time:
From Identity matrix: In matrix algebra, the identity matrix is a square matrix which has all the entries on the main diagonal equal to one and all the other, off-diagonal, entries equal to zero. The identity matrix acts as the identity element for matrix multiplication.
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)
- Puiseaux 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 Centre of a group:
From Identity element:
- Existence of an identity element is one of the properties of a group or monoid.
- An identity matrix is the identity element for matrix multiplication.
- Identity (mathematics)
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.
From Commutativity: a property of binary operations or of operators on a set
From Cantor set: The Cantor set is ... second countable, dense-in-itself, totally disconnected.
