Expressing a fraction of two determinants as a determinant [PDF]

open access: yesProceedings of the twenty-first international symposium on Symbolic and algebraic computation, 2008
Suppose the polynomials f and g in K[x1,...,xr] over the field K are determinants of non-singular m x m and n x n matrices, respectively, whose entries are in K ∪ x1,...,xr. Furthermore, suppose h = f/g is a polynomial in K[x1,..., xr]. We construct an s x s matrix C whose entries are in K ∪ x1,...,xr, such that h = det(C) and s = γ (m+n)6, where γ = O(

Maillet's Determinant [PDF]

open access: yesProceedings of the American Mathematical Society, 1955
Es sei \(p\) eine ungerade Primzahl, für ein zu \(p\) primes \(r\) sei \(R(r)\equiv r \pmod p\) mit \(0 < R (r) < p\), und nach Maillet \(D_p = \vert R(r s')\vert\), \(1\le r, s \le (p-1)/2\), wobei \(ss'\equiv 1\pmod p\) ist. Maillet fragte, ob \(D_p\ne 0\) für alle \(p\) sei. Verff.
