Abstract: | We study ther xr system of nonlinear elliptic equations
,a=1,2,...,r,x∈R
2, where λ τ 0 is a constant parameter,K = (Kab) is the Cartan matrix of a semi-simple Lie algebra, and βp is the Dirac measure concentrated atp
R
2. This system of equations arises in the relativistic non-Abelian Chern-Simons theory and may be viewed as a nonintegrable
deformation of the integrable Toda system. We establish the existence of a class of solutions known as topological multivortices.
The crucial step in our method is the use of the decomposition theorem of Cholesky for positive definite matrices so that
a variational principle can be formulated.
