Abstract
The subresultants play a fundamental role in elimination theory and compute r algebra. Recently they have been extended to Ore polynomials. They are de fined by an expression in the coefficients of Ore polynomials. In this pape r, we provide another expression for them. This expression is written in te rms of the solutions of Ore polynomials (in generic case). It is a generali zation of our previous paper where we gave expressions for the principal (f ormal leading) coefficients of subresultants. In this paper, we give expres sions for all the other coefficients.
