Action Principle for Scale Invariance and Applications (Part I)

Action Principle for Scale Invariance and Applications (Part I)

On the basis of a general action principle, we revisit the scale invariant field equation using the cotensor relations by Dirac (1973). This action principle also leads to an expression for the scale factor <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display=&...
