摘要：Recently, Hu, Huang and Lou [13] gave a general method for obtaining graphs which attain the minimum spectral radius with given independence number alpha >= inverted right perpendicularn/2inverted left perpendicular. In this paper, we determine the graphs that attain the minimum spectral radius among all unicyclic graphs with a given independence number alpha. Moreover, we characterize the graphs that attain the minimum spectral radius among all unicyclic graphs with a given domination number gamma, where 1 <= gamma <= inverted right perpendicularn/3inverted left perpendicular and gamma = n/2 for even n.
