Ruppeiner geometry is a geometric framework applied in the context of thermodynamics and black hole thermodynamics to analyze the properties of thermodynamic systems. It is named after George Ruppeiner, who introduced this approach in the 1990s. In this framework, the properties of a thermodynamic system are represented as a geometric structure, where thermodynamic state variables are treated as coordinates on a manifold.
