Outline of Final Research Achievements

Throughout this study, I wrote three papers. First, I gave a new and complete proof of Lp logarithmic Sobolev inequality by using the hypercontractivity of the solution of some Hamilton-Jacobi equation. Next, I clarified many properties of the inequality which is obtained by letting p→∞ in this Lp logarithmic Sobolev inequality. This was done by using Laplace transforms and the theory of regular variations. Finally, I investigated the set which determines the structure of solutions of Hamilton-Jacobi equations. This set plays the same role as the uniqueness set for boundary value problems.
