Claim: The Malgrange–Ehrenpreis theorem states that the differential equation, an equation that relates one or more functions and their derivatives, where P is a polynomial in several variables and δ is the Dirac delta function, has a distributional solution u.
Evidence: This means that the differential equation where P is a polynomial in several variables and δ is the Dirac delta function, has a distributional solution u. In mathematics, a differential equation is an equation that relates one or more functions and their derivatives.
