Cobalt aluminate is a complex oxide of cobalt and aluminum metals with the formula Co[Al2O4], blue crystals..
Triglyceride – fats, organic substances. They are obtained by combining triatomic alcohol Glycerol and Carboxylic acids.
( Saturated Fatty Acids: Stearic acid, Unsaturated Fatty Acids: Oleic acid, etc)
Let’s take a scalar unit 1 and multiply by a tri-vector i, we obtain the trivector i for the dual unit. We multiply p by i and obtain the dual trivector -1.
Vectors are dual to bivectors, and vectors to vectors for bivectors. The transition from the p-number A to the dual p-number iA = Ai is not an involution, since in the chain of maps A -> iA -> -A-> -iA -> A, the initial p-number A occurs only in 4 steps.
Thus, the space of vectors and bi-vectors has a duality.
