WebMay 15, 2024 · To compute the Gram determinant D n A g e n, we change the basis of the Temperley - Lieb algebra, T L n (d), so that in the new basis, the Gram matrix is a diagonal matrix. It follows from [1] that the change of basis is given by an upper triangular matrix with 1's on the diagonal. WebIn mathematics, Hadamard's inequality (also known as Hadamard's theorem on determinants [1]) is a result first published by Jacques Hadamard in 1893. [2] It is a bound on the determinant of a matrix whose entries are complex numbers in terms of the lengths of its column vectors.
