We reproduce the known expressions in terms of Bernoulli's polynomials for the gluons and quarks using the same formalism. Then we calculate the $\\mu$-dependence, both for small $\\mu$ as expansion, and numerically for finite $\\mu$.\n  One result is that the chemical potential only weakly changes the values of the condensed field, but quite strongly deepens the minima of the effective potential.
