Dibag, I.2015-07-282015-07-2819960021-8693http://hdl.handle.net/11693/10768A duality is established between left and right ideals of a finite dimensional Grassmann algebra such that if under the duality a left ideal I and a right ideal J correspond then I is the left annihilator of J and J the right annihilator of I. Another duality is established for two-sided ideals of the Grassmann algebra where two ideals that correspond are annihilators of each other. The dual of the principal ideal generated by an exterior 2-form is completely determined. Q 1996 Academic Press, Inc.EnglishGrassmann AlgebraDualityArticle10.1006/jabr.1996.0205
