A list of redlinks I've created with the intention of filling in at some time:
From Centre (mathematics):
- In an algebraic structure, elements that commute with every element of the structure
- The centre of a group, elements that commute with every group element
- The centre of a circle
- The centre of mass, centroid or barycentre of a geometrical figure
- In triangle geometry
- The centroid, intersection of the medians
- The circumcentre, intersection of the perpendicular bisectors of the sides, centre of the circle through the vertices
- The nine-point centre
- The orthocentre, intersection of the altitudes
- The incentre, centre of a circle tangent to the sides
- The excentres, centres of the three circles internally tangent to one side and externally to the other two
From Composition (mathematics):
- Function composition: the composition or successive application of functions
- Composition of relations
- Composition series in group theory
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 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.
