摘要：

Several problems in quantum field theory like QCD at high densities lead to complex-valued actions S with S : G --> C, where G is some group. Under the assumption that the complex Langevin process converges to a weakly stationary process we discuss the conditions under which it correctly simulates expectation values defined by complex weights. For technical reasons the discussion is restricted to (ill) and semisimple compact connected Lie groups like SU(n).
