Mathematical Fluid Mechanics and Related Topics - in honor of Professor Hideo Kozono's sixtieth birthday -   6 Sep 2018   
We rewrite the standard Hardy inequality in the form of an equality with radial derivative in Tex for Tex. Then we present another Hardy inequalities with radial and spherical derivatives in Tex for Tex. We al...

Research Grants & Projects

 
Project Year: Oct 2018 - Mar 2023
Mathematical Theory of turbulence by the method of modern analysis and computational science
Project Year: May 2012 - Mar 2017
The challenging problem on global well-posedness of the Navier-Stokes equations had been so fully investigated that several remarkable results are obtained. Furthermore, our DNS of the uniformly isotropic turbulence is still by far the larger comp...
Project Year: 2011 - 2012
Blow-up phenomenon of positive solutions to the Cauchy problem for nonlinear heat equation of Fujita type is studied. The blow-up phenomenon was first observed and proved by Hiroshi Fujita about half a century ago. There is a large literature on t...
Project Year: 2009 - 2013
We studied nonlinear elliptic equations arising in various fields of mathematical physics by means of variational analysis, ordinary differential equations, and viscosity techniques. We studied orbital stability of standing waves, explicit blow-up...
Project Year: 2009 - 2012
Various types of nonlinear PDEs (nonlinear elliptic equations, nonlinear diffusion equations, nonlinear wave equations, nonlinear Schrodinger equations) arising in physics and engineering were synthetically studied from the viewpoint of the theory...
