| Outline of Final Research Achievements |
We were able to establish the Aveiro discretization method that gives many numerical solutions of partial differential and integral equations by applying the theories of reproducing kernels and of Tikhonov regularization, and we published papers as applications. In particular, we got a general concept of representation of fractional functions and we found the division by zero as the typical case. We also succeeded in the numerical solutions for some convolution integral equations which involve non-linear equations.
Incidentally, we found a general theory among initial value problems in partial differential equations, reproducing kernels, eigenfunctions, integral transforms, and special function theory.
For the publication plan of a general theory of reproducing kernels, we complete a book manuscript with about 420 pages and we are discussing its publication with some publishers over about 2 years, however, at this moment we were not able to determine its publication, unfortunately.
