# Colloquium: Matrix Orbit Closures

Date Published: 02/01/17

Abstract: Two $R$ by $N$ matrices will be called $\textit{equivalent}$ if they differ by invertible row operations and rescaling of columns. The set of all matrices equivalent to your favorite matrix is called a $\textit{matrix orbit}$, and a $\textit{matrix orbit closure}$ consists of a matrix orbit and those matrices close to the orbit.
