我们证明了控制一维简单扩散动力学和某些化学反应过程的主方程给出了时间演化算符(哈密顿算符),它是Hecke代数的实现。在简单扩散的情况下,经过相似变换,得到可约厄米表示,而在其他情况下,它们是非厄米表示,对应于Hecke代数的超对称商。
We show that the master equation governing the dynamics of simple diffusion and certain chemical reaction processes in one dimension gives time evolution operators (Hamiltonians) which are realizations of Hecke algebras. In the case of simple diffusion one obtains, after similarity transformations, reducible hermitian representations while in the other cases they are non-hermitian and correspond to supersymmetric quotients of Hecke algebras.
