The matrix E = BBT − (d − 1)I is a symmetric matrix of order m. Since R(G) > √ d−1, we have λm(E) > 0. Hence E is a positive definite matrix whose diagonal entries are the integers degG(u)−(d−1) 62,u ∈ U. Since E is positive definite, these are all equal to 1 or 2 and hence the degrees of vertices in U are either ∆ or ∆−1.
