Subject:

For linear pfaffian systems of the Fuchs type on complex manifolds, the Frobenius conditions of the integrability were expressed across iterated Chen integrals and commutator relations in fundamental group of complement to the singularity divisor of the system. The multi-dimensional generalization of the Lappo–Danilevskii theory for fuchsian systems on complex projective spaces was formulated. For any hyperplane configuration in a complex projective space and an analytic deformation of the unit representation of the fundamental group of the complement to the hyperplane configuration the multi-dimensional Riemann–Hilbert problem is solved. The universal KZ operators (uKZ) and universal Calogero–Mozer–Sutherland(uCMS) hamiltonians associated to a root system are defined. On Bete and Dunkl manifolds are defined. The connections between uKZ and uCMS on Bete–Dunkl manifolds were studied. The $B_n$-Coxeter analog of the Drinfeld theory of the braided quasi-bialgebras and the $B_n$-analog of the main theorem in this theory (Drinfeld-Kohno theorem) was formulated and proved. On base of the $B_n$ quasi-bialgebra theory the universal Kontsevich–Vassiliev invarint of knots and links with additional order two symmetry was constructed. With point of view of the KZ equations the characterization of a simplest solutions of Schlesinger equations was given.
