چکیده

The topic of the paper is investigation homology groups $(2n+1)$-dimensional CW-complex $\mathbb{C}\Omega_n$. spaces $\mathbb{C}\Omega_n$ consist complex-valued functions and are analogue $\Omega_n$, widely known in approximation theory. have been introduced 2015 by A.M. Pasko who has built CW-structure using this established that simply connected. Note mentioned $\Omega_n$ constructed V.I. Ruban. Further found space dimensionalities $0, 1, \ldots, n, 2n-1, 2n, 2n+1$. goal present to find group $H_{n+1}\left ( \mathbb{C}\Omega_n \right )$. It proved $H_{n+1} \left )=\mathbb{Z}^\frac{n+1}{2}$ if $n$ odd )=\mathbb{Z}^\frac{n+2}{2}$ even.

Homology of Subgroups of Right-angled Artin Groups

We describe the (co)homology of a certain family of normal subgroups of right-angled Artin groups that contain the commutator subgroup, as modules over the quotient group. We do so in terms of (skew) commutative algebra of squarefree monomial ideals.

`-homology of right-angled Coxeter groups based on barycentric subdivisions

Associated to any finite flag complex L there is a right-angled Coxeter group WL and a contractible cubical complex ΣL on which WL acts properly and cocompactly, and such that the link of each vertex is L. It follows that if L is a triangulation of Sn−1, then ΣL is a contractible n-manifold. We establish vanishing (in a certain range) of the reduced `2-homology of ΣL in the case where L is the ...

Groups with Infinite Homology

A group is said to be acyclic if its reduced homology vanishes. Many interesting classes of groups have been discovered having this property ([2] is a useful survey). This is an indication that the reduced homology carries limited information. Here we obtain information about H̃(G) for a class of groups G that includes all locally finite groups and all soluble groups of finite rank. We show that...

Homology of jet groups

In this paper we compute the second homology of the discrete jet groups. Let R be the additive group of real numbers and R the multiplicative group of positive reals. The n jet group Jn = {rx+a2x + · · ·+anx | r ∈ R, ai ∈ R} is the group, under composition followed by truncation, of invertible, orientationpreserving real n-jets at 0. Consider the homomorphism D : Jn → R obtained by projecting o...
