  - Let G be a graph on the vertex set V(G) = {x1,…,xn} with the edge set E(G), and
    let R = K[x1,…, xn] be the polynomial ring over a field K. Two monomial ideals
    are associated to G, the edge ideal I(G) generated by all monomials xixj with
    {xi,xj} ∈ E(G), and the vertex cover ideal IG generated by monomials ∏xi∈Cxi for
    all minimal vertex covers C of G. A minimal vertex cover of G is a subset C ⊂
    V(G) such that each edge has at least one vertex in C and no proper subset of
    C has the same property. Indeed, the vertex cover ideal of G is the Alexander
    dual of the edge ideal of G. In this paper, for an unmixed bipartite graph G we
    consider the lattice of vertex covers LG and we explicitly describe the minimal
    free resolution of the ideal associated to LG which is exactly the vertex cover
    ideal of G. Then we compute depth, projective dimension, regularity and extremal
    Betti numbers of R/I(G) in terms of the associated lattice.@eng
