| Outline of Final Research Achievements |
The subject of this research is to obtain best evaluation of a Sobolev inequality. In continuous version, we have treated of Thomson cable (a continuous model) and a free boundary value problem for a 2M-th order operator (no lower terms). In discrete version, we have treated the Mobius ladder, C60 fullerene buckyball, the truncated regular M-hedron (M=4,6,8) and the Toeplitz graph. In each case, we have computed a best constant and family of best functions for the Sobolev inequality. These are important results to become the clue in studying the future Sobolev inequality.
