Odd-dimensional antisymmetric solution conjecture for noncommutative determinants

About 18 years old · traced to

Let nn be a positive integer, and let AA and BB be the matrices occurring in the identity eq.further.1⁡\operatorname{eq.further.1}, with parameters h1h_1 and qiq_i. A matrix is antisymmetric when it is equal to the negative of its transpose. Odd-dimensional antisymmetric-solution conjecture. If nn is odd and at least one of AA and BB is antisymmetric, then eq.further.1⁡\operatorname{eq.further.1} holds with

qi=(n−i)h1.q_i=(n-i)h_1.

This generalizes the antisymmetric solution observed for n=3n=3 and n=5n=5, but the paper does not establish it for all odd nn.
