Gualdani and N. Guillen. As shown in a region of the smooth potentials range under values of the interaction exponent (2), a weighted Poincar¨¦ inequality is a natural consequence of the traditional weighted Hardy inequality, which in turn implies that the norms of solutions propagate in the L1 space. Now, the L estimate is based on the work of De Giorgi, Nash, and Moser, as well as a few weighted Sobolev inequalities. %K Hardy¡¯s Inequality %K Sobolev Inequalities %K the Landau Equation %K L-Estimate %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=123897
