Wedge Reversion: A New Antisymmetry

What is chiral in one dimension is not chiral in a higher dimension.

Wedge Reversion antisymmetry was introduced as a means to classify all physical quantities in arbitrary dimensions.  The above image shows that an object that is chiral in N dimensions is no longer chiral in N+1 dimensions, and hence chirality is not a good metric to classify physical quantities.  Instead a new operation, Wedge reversion allows for such classification in arbitrary dimensions.  A recent article led by Hari and Jason in the Annual Reviews of Materials Research reviews this and other important antisymmetries and their applications.  Gopalan gave a zoom seminar at the Pittsburg Quantum Institute (PQI) on Sept 18, 2020 on this topic.  The video recording of the talk is on Youtube at this link.
