Graph theory and linear non invertible rank 1
WebSep 16, 2024 · This is true if your X is a square matrix. A Matrix is singular (not invertible) if and only if its determinant is null. By the properties of the determinant: det ( A) = det ( A T) And by Binet's theorem: det ( A ⋅ B) = det ( A) det ( B) Then, you're requesting that: det ( X T X) = 0. det ( X T) det ( X) = det ( X) 2 = 0.

WebApr 9, 2024 · This article establishes a connection between nonlinear DEs and linear PDEs on the one hand, and non-associative algebra structures on the other. Such a connection simplifies the formulation of many results of DEs and the methods of their solution.

We often call a linear transformation which is one-to-one an injection. Similarly, a linear transformation which is onto is often called a surjection.
