摘要
We prove the following conjecture by Carpentier, De Sole, and Kac: let K be a differential field and R be a differential subring of K. Let M be a matrix whose elements are differential operators with coefficients in R. Then, if M has degeneracy degree 1, the Dieudonne determinant of M lies in R.
