WebEin Differentialoperator ist in der Mathematik eine Funktion, die als Operator einer Funktion eine Funktion zuordnet und die Ableitung nach einer oder mehreren Variablen enthält. Insbesondere verschlechtern Differentialoperatoren die Regularität der Funktion, auf die sie angewendet werden.. Der wohl wichtigste Differentialoperator ist die … In special relativity, electromagnetism and wave theory, the d'Alembert operator (denoted by a box: $${\displaystyle \Box }$$), also called the d'Alembertian, wave operator, box operator or sometimes quabla operator (cf. nabla symbol) is the Laplace operator of Minkowski space. The operator is named after French … See more There are a variety of notations for the d'Alembertian. The most common are the box symbol $${\displaystyle \Box }$$ (Unicode: U+2610 ☐ BALLOT BOX) whose four sides represent the four dimensions of space-time and the … See more • "D'Alembert operator", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Poincaré, Henri (1906).
