components accordingly as each diagonal entry is positive or negative.

This can be proven by using induction on the fact that A has an eigenvector, by taking the quotient space by the eigenvector and inducting to show that A stabilises a flag, and is thus triangularizable with respect to a basis for that flag.

K The inverse of an upper triangular matrix, where extant, is upper triangular. )

Notice that this does not require inverting the matrix. {\displaystyle \operatorname {det} (xI-A)} ( 1

These are, respectively, the standard Borel subgroup B of the Lie group GLn and the standard Borel subalgebra

The transpose of an upper triangular matrix is a lower triangular matrix and vice versa.

{\displaystyle A_{k}} Other names used for these matrices are unit (upper or lower) triangular, or very rarely normed (upper or lower) triangular. , The product of an upper triangular matrix and a scalar is upper triangular.

The invertible ones among them form a subgroup of the general linear group, whose conjugate subgroups are those defined as the stabilizer of some (other) complete flag.

The sum of two upper triangular matrices is upper triangular.

2 The set of invertible triangular matrices of a given kind (upper or lower) forms a group, indeed a Lie group, which is a subgroup of the general linear group of all invertible matrices. {\displaystyle A_{i}} An atomic (upper or lower) triangular matrix is a special form of unitriangular matrix, where all of the off-diagonal elements are zero, except for the entries in a single column.

. … For instance, the sum of an upper and a lower triangular matrix can be any matrix; the product of a lower triangular with an upper triangular matrix is not necessarily triangular either.
