Outline of Final Research Achievements |
(1)The structure of K_2SL_2(R) was determined for several prime numbers p_1,...,p_n, where R = [1/p_1,...,1/p_n]. (2) We classified minimal locally affine Lie algebras. This is a joint work with Yoji Yoshii. (3) We characterized affine Kac-Moody groups using schemes and Galois descert. This is a joint work with A. Pianzola and T. Shibata. (4) We discussed some infinite root system obtained from H4 root systems in quaternion division ring, and obtained a new application to quantum bits. This is a joint work with Robert Moody.
