| Research Abstract |
(1)We made Matrix representations of Hecke algebras H(q,n) of n up to 18.
(2)We made a computer program bTd to assist knot researchers about the followings :
(2.1) to compute base tangle decompositions of n-tangles with 1<n<10.
(2.2) to compute HOMELY polynomials of knots and links using tangle decompositions
(3)HEAD INVESTIGATOR writes a paper "Base Tangle Decompositions of n-string tangles with 1<n<10" submitted to Experimental Mathematics
(4)We had founded two mutant knots K1 and K2 with 12 crossings such that P(K1^3;x,y) equals to P(K2^3;x,y) but P(K1^4;x,y) does not equal to P(K2^4 ;x,y).
(5)Our software bTd had been opened at http://amadeus.ics.nara-wu.ac.jp/~ochiai/
