Struct CoboundaryOperator 

pub struct CoboundaryOperator {
    pub chain: ChainComplex,
}

Coboundary operator δ^k : C^k → C^{k+1} (transpose of boundary ∂_{k+1}).

Cohomology groups H^k = ker δ^k / im δ^{k-1}.

Fields

chain: ChainComplex

Reference to the underlying chain complex.

Implementations

impl CoboundaryOperator

pub fn new(chain: ChainComplex) -> Self

Create coboundary from a chain complex.

pub fn coboundary_matrix(&self, k: usize) -> Vec<Vec<i32>>

Coboundary matrix δ^k : C^k → C^{k+1}.

This is the transpose of the boundary matrix ∂{k+1} : C{k+1} → C_k.

pub fn coboundary_rank(&self, k: usize) -> usize

Rank of the coboundary operator δ^k.

pub fn cup_product_is_compatible( _p: usize, _q: usize, _a_idx: usize, _b_idx: usize, ) -> bool

Cup product coefficient (simplified): returns 1 if cocycle a on dimension p and cocycle b on dimension q are compatible, else 0. This is a placeholder for the full cup product structure.
