ReductionPair

Short Description

Transcendental Liouvillian extensions are differential fields, in which one can model poly-logarithmic, hyperexponential, and trigonometric functions, logarithmic integrals, and their (nested) rational expressions. For such an extension, we construct, over the subfield of constants, a complement of the subspace of derivatives. The ReductionPair package, developed by Yiman Gao, Wenqiao Li, Ziming Li, not only provides a finite representation of this complement but also decomposes any element of the field into the sum of a derivative and a component lying in the complement.
