In this article, we are concerned with radial solutions for the best constant of the Cafarelii-Kohn-Nirenberg inequality. Firstly, we classify the radial solutions according to its asymptotic behavior as r-» 0 and r oo. Secondly, we investigate the structure of radial singular solutions. Lastly, we briefly discuss the Neumann problem related to the Cafarelli-Kohn-Nirenberg inequality.
