The Legendre Transformation, Duality and Functional Analytic Approach,periment is an example of a brilliant unification attempt. Basically, E. Mach suggested that the mass of the entire universe affects the local laws of mechanics so far discovered by man-kind. (We refer to his famous statement about the distance stars causing it all.)

,An Example of a Variational Approach to Mechanics Using “Different” Rules of Algebra,angian formulation “works”, the Hamilton’s canonical equations are displayed, everything seems to be in the right form. Upon a closer examination only one variational principle can be formulated at best. Even if the signs of the second FrSchet derivatives can be determined in the vicinity of a criti

Variational Principles of Continuum Mechanics,y, where we have to keep careful count of which elements belong to the space B and which belong to its dual B*, or even to B**. In the Hilbert space setting we can identify H with its dual H*, and all arguments are generally simplified.
