摘 要：

We compute solutions of Yang-Mills equation on Minkowski space by foliating different parts of it with non-compact coset spaces arising from the Lorentz group SO(1,3). The interior of the lightcone is foliated with hyperbolic space $H^3$ which is isomorphic to SO(1,3)/SO(3), while the exterior of the lightcone isfoliated with de Sitter space $dS_3$ which is isomorphic to SO(1,3)/SO(1,2). The equivariant reduction of the Yang-Mills system on these coset spaces yields a mechanical system with inverted potential admitting analytic solutions, including the "kink". We also present the energy-momentum tensor for these solutions.
