Extremal Rota-Baxter operators on matrix algebras
Vsevolod Gubarev
We classify all Rota-Baxter operators of weight on over a field of characteristic zero whose minimal polynomial has maximal degree and show that in both cases $λ=…
Simple double Lie algebras on the Laurent polynomial space
Vsevolod Gubarev
We construct a simple -double Lie algebra on for every nonzero . We then show that the analogous two-sided construction of weight zero is also simple. Both…
Injective Rota-Baxter operators of weight 1 on
Vsevolod Gubarev
We describe all injective Rota-Baxter operators of weight 1 on the polynomial algebra . When , the only one is . When $\mathrm{cha…
Inner post-Lie algebras and inner post-groups
V. Gubarev, Y. Li, Y. Sheng +1
In this paper, using extension theory and cohomological approach we introduce the notion of the obstruction class for an inner post-Lie algebra being induced by a Rota-Baxter opera…
Free Poisson Rota-Baxter algebra
Vsevolod Gubarev
We construct a free Poisson algebra endowed with a Rota-Baxter operator. The same construction works for a free Poisson algebra endowed with a Nijenhuis operator.
Rota-Baxter operators on the simple Jordan algebra of matrices of order two
Vsevolod Gubarev, Alexander Panasenko
We describe all Rota-Baxter operators of any weight on the space of matrices from considered under the product and usually denoted as $M_2(F)^{(+)…
