for which the local cohomology module H(x,y,z)(R) has a p-torsion element for every prime integer p, and consequently has infinitely many associated prime ideals. However, this example does not address Huneke’s question for rings containing a field, nor does it yield an example over a local ring. More recently, Katzman constructed the following example in [19]: let K be an arbitrary field and consider the hypersurface
