An Additive Decomposition in S-Primitive Towers
Hao Du, Jing Guo, Ziming Li +1
We consider the additive decomposition problem in primitive towers and present an algorithm to decompose a function in an S-primitive tower as a sum of a derivative in the tower an…

Additive Decompositions in Primitive Extensions
Shaoshi Chen, Hao Du, Ziming Li
This paper extends the classical Ostrogradsky-Hermite reduction for rational functions to more general functions in primitive extensions of certain types. For an element in suc…
