WebNov 16, 2024 · Abstract. The d’Alembertian is a linear second order differential operator, typically in four independent variables. The time-independent version (in three independent (space) variables is called the Laplacian operator. When its action on a function or vector vanishes, the resulting equation is called the wave equation (or Laplace’s equation).
