The order n>=2 L-polyomino consists of a vertical line of n squares with a single additional square attached at the bottom.

Given a positive integer n, a labeled n-digraph is a digraph whose vertex set is {1,...,n}.

A function that has a natural boundary.

A quantity involving primitive cube roots of unity which can be used to solve the cubic equation.

A lattice which is built up of layers of n-dimensional lattices in (n+1)-dimensional space. The vectors specifying how layers are stacked are called glue vectors. The order ...

If xsinalpha=sin(2beta-alpha), then (1+x)int_0^alpha(dphi)/(sqrt(1-x^2sin^2phi))=2int_0^beta(dphi)/(sqrt(1-(4x)/((1+x)^2)sin^2phi)).

A submodule L of a module M such that for any other nonzero submodule K of M, the intersection L intersection K is not the zero module. L is also called an essential ...
