Determination of (0,2)-regular sets in graphs

An eigenvalue of a graph is main iff its associated eigenspace is not orthogonal to the all-one vector j. The main characteristic polynomial of a graph G with p main distinct eigenvalues is _ (λ)=λ^−_0 λ^(−1)−_1 λ^(−2)-…-_(−2) λ−_(−1) and it has integer coefficients. If G has n vertices, the nxk wal...
