摘要：
Composition is an operation of replacing a variable in a polynomial with another polynomial. The main question of this paper is: What happens to subresultants under composition? The main contribution of the paper is to show that the subresultants ''almost'' commute with composition. This generalizes the well-known fact that the resultant is invariant under translation.
