项目摘要
Significant progress has been made on the one dimensional soliton cellular automata associated with quantum groups and related topics.The results (1)-(6) obtained in the three years are explained herewith.(1) On D type tropical R, its bilinear form was found and the tau functions of the DKP hierarchy was shown to be a solution of it. By a systematic reduction, similar results were obtained for the affine Lie algebras of type C type and twisted A.(2) For the cellular automata with capacity greater than one, the time evolution was described with an explicit algorithm in terms of the motion of particles and antiparticles which undergo the pair creation and annihilation.(3) A quantization of the box-ball system was constructed from a certain limit of a vertex model, which tends to the original one at q=0. Two kinds of norm were introduced and their property was investigated.(4) A box-ball system with a reflecting end was constructed. The soliton degrees of freedom was extracted, scattering and reflection rules are clarified.A solution of the boundary integrability condition is found at the tropical setting.(5) A new description of the KKR bijection, the crux in proving the fermionic formula, was obtained purely in terms of the combinatorial R in crytal base theory.A similar description was conjectured for all the other KKM crystal case. The result yiled the inverse scattering formalism of the box-ball system.(6) Periodic box-ball systems were extended to the KKM crystal and A type KM crystal cases and conjectures were put forward on the state counting formula and the generic dynamical period.For the symplest A type case, the initial value problem was completely solved by unifying the Bethe ansatz at q=0 and q=1.
与量子群相关的一维孤子元胞自动机及其相关课题取得了重大进展。在此对三年中获得的(1)-(6)结果进行说明。(1)在D型热带R上,发现了它的双线性形式,并证明了DKP层次的tau函数是它的解。(2)对于容量大于1的元胞自动机,用一种显式算法描述了粒子和反粒子在产生对和湮灭过程中的运动的时间演化。(3)从顶点模型的某一极限出发,构造盒球系统的量化,使其在q=0时趋向于原始模型。介绍了两种范数,并研究了它们的性质。(4)构造了带反射端盒球系统。提取了孤子的自由度,阐明了孤子的散射和反射规律。在热带背景下,得到了边界可积条件的一个解。(5)利用晶体基理论中的组合R,对证明费米子公式的关键——KKR双射进行了新的描述。类似的描述被推测为所有其他KKM水晶盒。结果得到了盒子球系统的逆散射形式。(6)将周期盒球系统推广到KKM晶体和A型KM晶体情况,提出了状态计数公式和一般动力学周期的猜想。对于最简单的A型情况,通过统一q=0和q=1处的Bethe函数,完全解决了初值问题。
