In this work we consider the comparison of planar and planar parquet approximations for zero-dimensional hermitian matrix models. We discuss how the parquet approach reproduces planar one for matrix model $\phi^4$, multi-trace model, two-matrix model and the Goldstone matrix model.
Keywords: matrix models, planar approximation, Schwinger–Dyson equations
Mots-clés : parquet equations.
