Resumen:
Let B(n,q) be the class of block graphs on n vertices having all their blocks of the same size. We prove that if G belongs to B(n,q) has at most three pairwise adjacent cut vertices then the minimum spectral radius is attained at a unique graph. In addition, we present a lower bound for the spectral radius when G belongs to B(n,q).
