Negation is a self dual logical operator.
3.
This great circle is self dual.
4.
The Painlev?equations are all reductions of the self dual Yang-Mills equations; see.
5.
Furthermore, observe that Heyting algebras are not self dual, and thus using filters in place of ideals yields different theorems in this setting.
6.
A path that traverses 6 vertices solely along edges, resides in the dual of this polytope, which is itself since it is self dual.
7.
Because the six homogeneous coordinates of a line can be obtained from the join of two points or the intersection of two planes, the line is said to be self dual in projective space.
