Clariant is a speciality chemicals company, formed in 1995 as a spin-off from Sandoz. The company is focused on four business areas: care chemicals (consumer and industrial); catalysis; natural resources (oil & mining, minerals); and plastics & coatings.

In mathematics, the symmetry of second derivatives (also called the equality of mixed partials) refers to the possibility under certain conditions (see below) of interchanging the order of taking partial derivatives of a function

At some point a longer list will become a List of Great Mathematicians rather than a List of Greatest Mathematicians. I've expanded my original List of Thirty to an even Hundred, but you may prefer to reduce it to a Top Seventy, Top Sixty, Top Fifty, Top Forty or Top Thirty list, or even Top Twenty, Top Fifteen or Top Ten List.

Equations of the first order and higher degree, Clairaut’s equation. Singular solutions and extraneous loci. Discriminant of a differential equation.

Der Satz von Schwarz (nach Hermann Amandus Schwarz; wird auch Satz von Clairaut genannt; oder auch Young-Theorem) ist ein Satz der Mathematik in der Differentialrechnung mehrerer Variablen.

Courbe étudiée par Villalpando en 1606, et par Münger en 1894. Autres noms : biovale, courbe proportionnatrice (nom donné par Villalpando).

In the section we will take a look at higher order partial derivatives. Unlike Calculus I however, we will have multiple second order derivatives, multiple third order derivatives, etc. because we are now working with functions of multiple variables. We will also discuss Clairaut’s Theorem to help with some of the work in finding higher order ...
