We describe the support of-finite-modules over polynomial ringsof prime characteristic. Our description yields an algorithm to compute the support of such modules; the complexity of our algorithm is also analysed. To the best of our knowledge, this is the first algorithm to avoid extensive use of Gröbner bases and hence of substantial practical value. We also use the idea behind this algorithm to prove that the support ofis Zariski closed for each idealofwhereis noetherian commutative ring of prime characteristic with finitely many isolated singular points and().
