# Testing the gaussian expansion method in exactly solvable matrix models

@article{Nishimura2003TestingTG, title={Testing the gaussian expansion method in exactly solvable matrix models}, author={Jun Nishimura and Toshiyuki Okubo and Fumihiko Sugino}, journal={Journal of High Energy Physics}, year={2003}, volume={2003}, pages={057-057} }

The gaussian expansion has been developed since early 80s as a powerful analytical method, which enables nonperturbative studies of various systems using `perturbative' calculations. Recently the method has been used to suggest that 4d space-time is generated dynamically in a matrix model formulation of superstring theory. Here we clarify the nature of the method by applying it to exactly solvable one-matrix models with various kinds of potential including the ones unbounded from below and of…
