Phys. VL - 20 IS - 2 SE - Papers DO - 10.15625/0868-3166/20/2/2158 UR - https://vjs.ac.vn/index.php/cip/article/view/2158 SP - 113 AB - The covariant wedge products of tetrads in General Relativity are introduced and related field equations are derived. The electromagnetic dual field is treated in detail and it is shown that this field is closely related with one component field, which is eigenfunction of d'Alembertian operator. The formalism is developed to incorporate internal symmetry. ER -
