Species of Rota-Baxter algebras by rooted trees, twisted bialgebras and Fock functors

Loic Foissy, Li Guo, Xiao-Song Peng +2

As a fundamental and ubiquitous combinatorial notion, species has attracted sustained interest, generalizing from set-theoretical combinatorial to algebraic combinatorial and beyon…

Rota-Baxter operators, differential operators, pre- and Novikov structures on groups and Lie algebras

Xing Gao, Li Guo, Zongjian Han +1

Rota-Baxter operators on various structures have found important applications in diverse areas, from renormalization of quantum field theory to Yang-Baxter equations. Relative Rota…

Twisted Mahler discrete residues

Carlos E. Arreche, Yi Zhang

Recently we constructed Mahler discrete residues for rational functions and showed they comprise a complete obstruction to the Mahler summability problem of deciding whether a give…

Extending structures of Rota-Baxter Lie algebras

Xiao-song Peng, Yi Zhang

In this paper, we first introduce the notion of an extending datum of a Rota-Baxter Lie algebra through a vector space. We then construct a unified product for the Rota-Baxter Lie…

Matching Rota-Baxter algebras, matching dendriform algebras and matching pre-Lie algebras

Xing Gao, Li Guo, Yi Zhang

We introduce the notion of a matching Rota-Baxter algebra motivated by the recent work on multiple pre-Lie algebras arising from the study of algebraic renormalization of regularit…

Weighted infinitesimal unitary bialgebras, pre-Lie, matrix algebras and polynomial algebras

Yi Zhang, Jiawen Zheng, Yanfeng Luo

Motivated by the classical comatrix coalgebra, we introduce the concept of a Newtonian comatrix coalgebra. We construct an infinitesimal unitary bialgebra on a matrix algebra and a…
