In this paper, through theoretical derivation, a functional relationship is revealed, demonstrating that the variation in time between objects in relative motion depends on both their relative velocity and the finite propagation speed of light. By applying the relationship of time change to the theory of classical mechanics, it can be concluded that the interaction force between objects are also related to the relative motion velocity. Due to the introduction of the speed of light in the formula of classical mechanical theory, the applicable scope of classical mechanics theory is effectively expanded, so that it is not only applicable to the calculation of low speed moving objects, but also to the calculation of high speed moving objects. Subsequently, through careful derivation within this new framework, several fundamental laws of classical electromagnetism were derived, the results of which strongly support the validity of the new functional relationship

It is known that the Fourier transformation of the square of (6j) symbols has a simple expression in the case of su(2) and Uq(su(2)) when q is a root of unit. The aim of the present work is to unravel the algebraic structure behind these identities. We show that the double cross product construction H1⋈H2 of two Hopf algebras and the bi-cross-product construction H2*⧑H1 are the Hopf algebra structures behind these identities by analyzing different examples. We study the case where D=H1⋈H2 is equal to the group algebra of ISU(2), SL(2,C) and where D is a quantum double of a finite group of SU(2) and of Uq(su(2)) when q is real.

I n-situ x-ray data has been obtained on 99.99% pure cerium at 50 and 52 kbar with the use of a Bragg-Brentano parafocusing x-ray reflection technique under quasihydrostatic conditions, with a thermal cycling procedure. Our results, based upon 22 experimental diffraction lines, indicate that cerium metal exhibits a definite crystallographic transition from fcc to hcp symmetry at 51±1 kbar with a ?7% volume reduction. Previous results are discussed in light of indexing reliability calculations.
