In 1986, R.A.Brualdi and E.S. Solheid posed the problem of maximizing the spectral radius and determining the extremal graph for a given class of graphs. Much attention has been paid for this question in the past decades. The signless Laplacian spectral radius of bicyclic graphs with given order and pendant vertices are focused on. The maximal spectral radius together with the unique extremal graph is determined.
