Liouvillian Solutions of Difference-Differential Equations
Ruyong Feng, Michael F. Singer, Min Wu
For a field k$with an automorphism σand a derivation δ, we introduce the notion of liouvillian solutions of linear difference-differential systems {σ(Y) = AY, δ(Y) = BY} over k and…
Classification of Ramification Systems for Symmetric Groups
Shouchuan Zhang, Min Wu, Hengtai Wang
We obtain the formula computing the number of isomorphic classes of ramification systems with characters over group () and their representatives.
Classification of Element Systems over Finite Commutative Groups
Junqin Li, Shouchuan Zhang, Hengtai Wang +1
We obtain the formula computing the number of isomorphic classes of element systems with characters over finite commutative group .
A Recursive Method for Determining the One-Dimensional Submodules of Laurent-Ore Modules
Ziming Li, Michael F. Singer, Min Wu +1
We present a method for determining the one-dimensional submodules of a Laurent-Ore module. The method is based on a correspondence between hyperexponential solutions of associated…
