Web Definition: Chain
In set theory, a chain is a total order subset of a poset. Condition. In algebraic topology, a simplicial k - chain is a formal linear combination of k - simplices. Integration is defined on chains by taking the linear combination of integrals over the simplices in the chain with coefficients typically integers. The set of all k -chains forms a group & the sequence of these groups is called a simplicial complex. The boundary of a chain is the linear combination of boundaries of the simplices in the chain. The boundary of a k -chain is a -chain. Note that the boundary of a simplex is not a simplex, but a chain with coefficients 1 or -1. The boundary of a directed path is the formal difference of its endpoints. The boundary of the triangle is a formal sum of its edges with signs arranged to make the traversal of the boundary counterclockwise. A chain is called a cycle when its boundary is zero. A chain that is the boundary of another chain is called a boundary. Boundaries are cycles, so chains form a chain complex, whose homology groups are called simplicial homology groups.
