| Research Abstract |
The purpose of this research is to construct a software to assist researches about Knot Theory. It assists to compute all polynomial invariants and in particular, parallel polynomial invariants related with knots and links. We had constructed a computer software, Knot Theory by Computer which works on Windows 95 and Windows NT.The software has the following features :
(1)to construct knots and links by mouse tracking,
(2)to deform knots by mouse operations,
(3)to visualize knots and links by 3-dimensional computer graphics,
(4)to compute all polynomial invariants which have already known,
(5)to compute 3-parallel polynomial invariants associated with 3,4, and 5 braids
(6)to recognize to whether a knot to be trivial or not (but not complete),
This software will be distributed worldwide through leternet (ftp.ics.nara-wu.ac.jp) by the end of April, 1998. In future research, we will construct new features to compute 4-parallel polynomial invariants associated with 4-braids and establish a method to construct any irreducible representations associated with Hecke algebras. The well known Lascoux-Schutzenberger's method is correct by up to 13 of braid index but false greater than 13.
