%0 Journal Article %T Some Properties of First Order Differential Operators %A Servais Cyr Gatse %J Advances in Pure Mathematics %P 934-943 %@ 2160-0384 %D 2019 %I Scientific Research Publishing %R 10.4236/apm.2019.911046 %X We study some properties of first order differential operators from an algebraic viewpoint. We show this last can be decomposed in sum of an element of a module and a derivation. From a geometric viewpoint, we give some properties on the algebra of smooth functions. The Dirac mass at a point is the best example of first order differential operators at this point. This allows to construct a basis of this set and its dual basis. %K Commutative Algebra %K Differential Operators %K Module of Differentials %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=96636
