Matrix string theory

Matrix string theory is a theoretical framework in string theory that aims to describe fundamental aspects of quantum gravity and the behavior of string-like objects at a microscopic level. It is particularly associated with the study of non-perturbative aspects of string theory and offers a way to understand the dynamics of strings and the underlying spacetime structure through matrix models. The key idea behind matrix string theory is to represent strings or branes as matrices, which are mathematical objects that can encode information about multiple degrees of freedom.
