👉 The Laplacian is a mathematical operator that describes the variations in a function or its derivatives over a region. It was named after Édouard Le Cam, a French mathematician who developed it extensively during his lifetime. The Laplacian of a function f(x, y) on a two-dimensional domain D is defined as: ∇·(f ∇ · f) where ∇ is the gradient operator that takes a vector field F to its covariant derivative (F = ∇
