Laplace operator: Vector Laplacian, Motivation & Generalizations

In mathematics, the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a scalar function on Euclidean space. It is usually denoted by the symbols ⁠ ∇ ⋅ ∇ {\displaystyle \nabla \cdot \nabla } ⁠, ∇ 2 {\displaystyle \nabla ^{2}} (where ∇ {\displaystyle \nabla } is the nabla operator), or ⁠ Δ {\displaystyle…
