Vitagliano %J Mathematics %D 2011 %I arXiv %R 10.1016/j.geomphys.2011.05.003 %X Diffieties formalize geometrically the concept of differential equations. We introduce and study Hamilton-Jacobi diffieties. They are finite dimensional subdiffieties of a given diffiety and appear to play a special role in the field theoretic version of the geometric Hamilton-Jacobi theory. %U http://arxiv.org/abs/1104.0162v2
