| Outline of Final Research Achievements |
(1) Existence of the solutions for the best constants of the Caffarelli-Kohn-Nirenberg type inequalities, continuity with respect to parameters of the best constant, symmetry breaking were studied systematically. For p=1, the Caffarelli-Kohn-Nirenberg type inequalities were established by effective use of isoperimetric inequalities, and symmetry breaking in p=1 was proved. (2) A theory of super logarithm based on logarithmic infinite product was introduced, and existence of infinitely many missing term was shown for the weighted Hardy type inequalities. (3) Differential equations characterizing super logarithm was studied to deal with elliptic equations with nonlinear term of very fast growth order.
