Struct BarResolution 

pub struct BarResolution {
    pub group_name: String,
    pub num_steps: usize,
    pub ranks: Vec<usize>,
}

The bar resolution of k over the group algebra kG.

B_n(kG) = kG ⊗ k^{n+1} (as a kG-module).

Fields

group_name: String

The group name.

num_steps: usize

Number of computed steps.

ranks: Vec<usize>

Rank of each bar module B_n.

Implementations

impl BarResolution

pub fn new(group_name: &str, group_order: usize, num_steps: usize) -> Self

Create a bar resolution up to the given number of steps.

For a group G with |G| = order, B_n = (kG)^{|G|^n}.

pub fn rank_at(&self, n: usize) -> usize

The rank of B_n.

Trait Implementations
