On the Best Constant Problem for a Class of Mixed-Norm Hardy Inequalities
Keyword(s):
AbstractIn this paper, we obtain the best constant and the equality condition for a class of mixed-norm Hardy inequalities when the weight is a power function. By building and solving the corresponding Euler equation, we look for the best constant and the optimal function. One of the main ingredients is to introduce two key auxiliary functions so that the corresponding equalities are derived.
