A fixed point for which the eigenvalues are complex conjugates.

A polynomial p(x)=sumc_ix^i is said to split over a field K if p(x)=aproduct_(i)(x-alpha_i) where a and alpha_i are in K. Then the polynomial is said to split into linear ...

A link L is said to be splittable if a plane can be embedded in R^3 such that the plane separates one or more components of L from other components of L and the plane is ...

A method for computing an Egyptian fraction. This method always terminates (Beeckmans 1993).

A three-dimensional knot spun about a plane in four dimensions. Unlike suspended knots, spun knots are smoothly embedded at the poles.

An n×n array is called a square array. Considered as a matrix, a square array is called a square matrix.

A polynomial which is not necessarily an invariant of a link. It is related to the dichroic polynomial. It is defined by the skein relationship ...

A square grid is a grid formed by tiling the plane regularly with squares.

A function f(x) is said to be square integrable if int_(-infty)^infty|f(x)|^2dx is finite.

A number taken to the power 2 is said to be squared, so x^2 is called "x squared." This terminology derives from the fact that the area of a square of edge length x is given ...
