The equation $X^{⊤} A X = B$ with $B$ skew-symmetric: How much of a bilinear form is skew-symmetric?

Alberto Borobia, Roberto Canogar, Fernando De Terán

Given a bilinear form on $C^{n}$ , represented by a matrix $A \in C^{n \times n}$ , the problem of finding the largest dimension of a subspace of $C^{n}$ such that t…
