This monograph is a synthesis of the speculation of the pairwise coupling of the angular momenta of arbitrarily many self sufficient platforms to the whole angular momentum within which the common position of doubly stochastic matrices and their quantum-mechanical probabilistic interpretation is a huge subject matter. A uniform point of view is gifted in accordance with the constitution of binary timber. This features a systematic approach for the overview of all 3n-j coefficients and their courting to cubic graphs. a couple of topical topics that emerge certainly also are built, akin to the algebra of permutation matrices, the houses of magic squares and an linked generalized Regge shape, the Zeilberger counting formulation for alternating signal matrices, and the Heisenberg ring challenge, seen as a composite approach during which the whole angular momentum is conserved. The readership is meant to be complicated graduate scholars and researchers drawn to studying in regards to the dating among unitary symmetry and combinatorics and tough unsolved difficulties. the numerous examples serve in part as workouts, yet this monograph isn't really a textbook. it's was hoping that the themes awarded advertise extra and extra rigorous advancements that result in a deeper knowing of the angular momentum houses of complicated structures seen as composite wholes 1. simple suggestions and formulation -- 2. pressure services -- three.

Co = 0, that is to say, the actual displacement function is given on LQ and the others on Lj's are given relative to the translations so that C\,... ,Cm are undetermined. 12) should be changed to j = 0 , 1 , . . 12') where Co = 0, C\,... ,Cm are undetermined constants and g*(t) is a given function. 14). We may also regard all the constants CQ,CI,... 12) as undetermined, that is, the displacement on each Lj (j > 0) is given only relative to a translation. 14') which means the origin is fixed.

1) are unique. In fact, it is not necessary that 0(0) = 0 though Im

Therefore, besides the unknown functions (j>o(z), ipo(z), there are m — 1 undetermined constants. 10) in order to guarantee the unique solvability. Such a situation is possible: the principal vector of the external stresses on each Lj is given, while only the displacement relative to a translation is given on each LJ: Uj(t)+ivj(t) (the actual displacement is Uj(t)+ivj(t)+Cj, where Cj is an undetermined constant, j = 1,... , TO). 10). 9) for the unique solvability. As above, without loss of generality, again we may always assume there are no stresses and rotation at oo, and if Xj + iYj is given, we may assume it is zero.
