In mathematics, the Yang–Mills–Higgs equations are a set of non-linear partial differential equations for a Yang–Mills field, given by a connection, and a Higgs field, given by a section of a vector bundle (specifically, the adjoint bundle).
These equations are with a boundary condition where These equations are named after Chen Ning Yang, Robert Mills, and Peter Higgs.
They are very closely related to the Ginzburg–Landau equations, when these are expressed in a general geometric setting.
Kapitanskii have shown that the Cauchy problem for hyperbolic Yang–Mills–Higgs equations in Hamiltonian gauge on 4-dimensional Minkowski space have a unique global solution with no restrictions at the spatial infinity.
Furthermore, the solution has the finite propagation speed property.
