Applications of the generalized Sylvester matrix

摘要

Recently a Sylvester matrix for several polynomials has been defined, establishing the relative primeness and the greatest common divisor of polynomials. Using this matrix, we perform qualitative analysis of several polynomials regarding the inners, the bigradients, Trudi's theorem, and the connection of inners and the Schur complement. Also it is shown how the regular greatest common divisor of m+1 (m>1) polynomial matrices can be determined.
