| Abstract: | In this paper, it is proved that the set of relative homology groups of I(G)modulo the independence complexes of vertex-deleted subgraphs of G is reconstructible andthe set of relative homology groups of N(G) modulo the neighbourhood complexes of vertexdeleted subgraphs of G is conditionally reconstructible. |

| Keywords: | graph neighbourhood complexes independence complexes relative homology group reconstruction |
