Green{close_quote}s functions are valuable analytical tools for solving a myriad of boundary-value problems in mathematical physics. Here, Green{close_quote}s functions of the Laplacian and biharmonic operators are derived for a three-dimensional toroidal domain. In some sense, the former result may be regarded as {open_quotes}standard,{close_quotes} but the latter is most certainly not. It is shown that both functions can be constructed to have zero value on a specified toroidal surface with a circular cross section. Additionally, the Green{close_quote}s function of the biharmonic operator may be chosen to have the property that its normal derivative also vanishes there. A {open_quotes}torsional{close_quotes} Green{close_quote}s function is derived for each operator which is useful in solving some boundary-value problems involving axisymmetric vector equations. Using this approach, the magnetic vector potential of a wire loop is computed as a simple example. {copyright} {ital 1997 American Institute of Physics.}
