SUMMARY
The discussion focuses on calculating Gaussian curvature for a given metric defined as ds² = f dr² + g dθ² + h dϕ², where f, g, and h are functions of r and θ. To compute Gaussian curvature in the r-θ, r-ϕ, and θ-ϕ planes, the Brioschi formula is applicable when the surface is embedded in a 2D space. For higher-dimensional spaces, the Riemann Curvature Tensor and the determinant of the metric matrix are utilized, specifically K = R₁₂₁₂/g, where K represents Gaussian curvature.
