• Under construction
MaKR was created out of my own needs and is only a small part. I'm not an expert in knowledge information processing or numerical computing.

This page is intended as an introductory note to mathematical research with computing.


MaKR (=Mathematical Knowledge Repository, named by myself)[Oh18] is designed as an individual tool, which also works as an assistant that helps thinking about the mathematical subjects. MaKR is a mathematical Web-based system whose contents are glued by an original LaTeX-like formatting language (low-)OFM that are designed under the concept of pushdown automaton, whose translator form OFM to HTML is written in Perl and named ofm2html. For the management of resources, a special-purpose Web browser called MaKRV is designed. Recently, The use of MathJax enhanced the mathematical representation.

Programming language:
The browser was created from a sample modifying the Microsoft Foundation Class (MFC, C++), while the conversion from original format (OFM) to HTML was made in Perl . For security reasons, there is no server-side programming such as CGI or PHP on the internet. The MaKR codes written by OFM are converted to HTML in my computer and uploaded.

Formulas in images MathType Some mathematical symbols are broken into graphics, so they are embedded using Illustrator.
Photo processing
Photos (Miyajima , Paris, etc.) are taken by myself, (some of them may have been purchased).


Some samples are in SoptS .
Only content related to SoptS will be included here; other sites will be added later, such as a description of FreeFEM.


Information about the page: The current position is painted circle in the diagram below. Blue is the main MaKR and orange is a duplicate for MaKR's public use, where dashed line means the connection to the private area. The dashed lines are only connections to main MaKR.
