Weighted Trudinger-Moser inequalities in the subcritical Sobolev spaces and their applications

Masahiro Ikeda, Megumi Sano, Koichi Taniguchi

We study boundedness, optimality and attainability of Trudinger-Moser type maximization problems in the radial and the subcritical homogeneous Sobolev spaces $\dot{W}^{1,p}_{0, \te…

On eigenvalue problems involving the critical Hardy potential and Sobolev type inequalities with logarithmic weights in two dimensions

Megumi Sano, Futoshi Takahashi

We consider the two-dimensional eigenvalue problem for the Laplacian with the Neumann boundary condition involving the critical Hardy potential. We prove the existence of the secon…

Critical Hardy inequality on the half-space via the harmonic transplantation

Megumi Sano, Futoshi Takahashi

We prove a critical Hardy inequality on the half-space by using the harmonic transplantation. Also we give an improvement of the subcritical Hardy inequality on the half-space, whi…

Improvements and generalizations of two Hardy type inequalities and their applications to the Rellich type inequalities

Megumi Sano

We give improvements and generalizations of both the classical Hardy inequality and the geometric Hardy inequality based on the divergence theorem. Especially, our improved Hardy t…

Minimization problem associated with an improved Hardy-Sobolev type inequality

Megumi Sano

We consider the existence and the non-existence of a minimizer of the following minimization problems associated with an improved Hardy-Sobolev type inequality introduced by Ioku.…
