Div rot grad
WebWirbelfelder rot(v) sind damit quellfrei. Den Beweis zu diesem span... Für ein zwei mal stetig differenzierbares Vektorfeld v: ℝ³ ℝ³ gilt, dass div(rot(v))=0. There is the fourth relevant differential operator, called rotor, curl, or rotation. This operator acts on vectors. Contrary to \,\text { grad }\, and \mathrm div, the \,\text { rot }\, as a vector function of a vector argument can be defined only in 3 D.
