Abstract
This chapter reviews and elaborates on the operators from Geometric algebra on G2 to G3. This algebra is attributed to Hermann Grassmann [Die lineare Ausdehnungslehre, ein neuer Zweig der Mathematik 1842]. It is formed by two main operators, the outer product and the inner product, it also includes the element called bivector. Here, we review their properties and their application in space.
