The \( \frac{1}{N} \) expansion is a technique frequently used in theoretical physics, particularly in the context of quantum field theory, many-body physics, and statistical mechanics. The idea behind this expansion is to develop an approximation for a system that depends on a large parameter \( N \), which can represent the number of particles, number of colors in gauge theories, or other relevant quantities.
