Nettet4. apr. 2016 · Let's first find the Lie algebra g l n ( K) of the general linear group GL n ( K). Because this is a matrix group then X ∈ g l n ( K) if and only if. I + ε X ∈ GL n ( K). In other words, we want ε ↦ I + ε X to be an infinitesimal curve through the identity of the Lie group (this is not just a hand-wavey explanation, but a truly ... In mathematics, a triangular matrix is a special kind of square matrix. A square matrix is called lower triangular if all the entries above the main diagonal are zero. Similarly, a square matrix is called upper triangular if all the entries below the main diagonal are zero. Because matrix equations with triangular matrices are easier to solve, they are very important in numerical analysis. By the LU decomposition algorithm, an invertible matrix may be written as the …
