Cohomology and Deformations of Relative Rota–Baxter Operators on Lie-Yamaguti Algebras
MathematicsIn this paper, we establish the cohomology of relative Rota–Baxter operators on Lie-Yamaguti algebras via the Yamaguti cohomology. Then, we use this type of cohomology to characterize deformations of relative Rota–Baxter operators on Lie-Yamaguti ...

International Journal of Mathematics and Mathematical Sciences, 2006 We discuss the calculation of integral cohomology ring of LG/T and ΩG. First we describe the root system and Weyl group of LG, then we give some homotopy equivalences on the loop groups and homogeneous spaces, and calculate the cohomology ring structures

Group cohomology of the universal ordinary distribution [PDF]
, 1999 For any odd squarefree integer r, we obtain a complete description of the Gra GalQOm r U=Q group cohomology of the universal ordinary distribution Ur in this paper.

Cohomology of Metacyclic Groups [PDF]
Transactions of the American Mathematical Society, 1991 group N by a finite cyclic group K . Using homological perturbation theory, we introduce the beginning of a free resolution of the integers Z over the group ring ZG of G in such a way that the resolution reflects the structure of G as an extension of N by K, and we use this resolution to compute the additive structure of the integral cohomology of G in

Cohomology of the minimal nilpotent orbit
, 2007 We compute the integral cohomology of the minimal non-trivial nilpotent orbit in a complex simple (or quasi-simple) Lie algebra. We find by a uniform approach that the middle cohomology group is isomorphic to the fundamental group of the sub-root system ...

Higher order group cohomology and the Eichler-Shimura map [PDF]
, 2007 Higher order group cohomology is defined and first properties are given. Using modular symbols, an Eichler-Shimura homomorphism is constructed mapping spaces of higher order cusp forms to higher order cohomology groups.

Topology and its Applications, 2002 AbstractLet W be a finitely generated Coxeter group. We describe a method which is useful in computing the cohomology of W with local coefficients. It is based on the determination of an explicit combinatorial resolution of Z over Z[W] (developed in a previous paper) which grows polynomially with the dimension.

On the Second Cohomology of Kähler Groups [PDF]
Geometric and Functional Analysis, 2011 Carlson and Toledo conjectured that any infinite fundamental group $ $ of a compact K hler manifold satisfies $H^2( ,\R)\not =0$. We assume that $ $ admits an unbounded reductive rigid linear representation. This representation necessarily comes from a complex variation of Hodge structure ($\C$-VHS) on the K hler manifold.
