I'd be very interested in continue a mathematical conversation
Taken from my signature: time independence - [∂E(g)]²=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] expresses the square of energy as vector and scalar product while mass independence - ¶a(t)·¶r(t)=c² expresses a scalar product. Could this scalar product be part of Hilbert space?
Time independence: [∂E(g)]²=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] and Mass independence: ¶a(t)·¶r(t)=c²
