STRUCTURES ASSOCIATED WITH THE BORROMEAN RINGS' COMPLEMENT IN THE POINCARE<acute accent> BALL

Guided by physical needs, we deal with the rotationally isotropic Poincar<acute accent>e ball, when considering the complement of Borromean rings embedded in it. We consistently describe the geometry of the complement and realize the fundamental group as isometry subgroup in three dimensions. Applying this realization, we reveal normal stochastization and multifractal behavior within the examined model of directed random walks on the rooted Cayley tree, whose six- branch graphs are associated with dendritic polymers. According to Penner, we construct the Teichmu<spacing diaeresis>ller space of the decorated ideal octahedral surface related to the quotient space of the fundamental group action. Using the conformality of decoration, we define six moduli and the mapping class group generated by cyclic permutations of the ideal vertices. Intending to quantize the geometric area, we state the connection between the induced geometry and the sine-Gordon model. Due to such a correspondence we obtain the differential two-form in the cotangent bundle of the moduli space.
