摘要：
自1923年Burchnall-Chaundy的开创性工作以来，常微分算子的交换环与代数曲线之间的对应关系已被深入广泛地研究。本文概述了通过微分代数和符号计算使该对应关系在计算上有效的最新进展。常微分算子$L$的中心化子是一个极大交换环，即谱曲线$Γ$的仿射环。在已知中心化子的有限生成集的情况下，描述了$Γ$的定义理想。此外，$L-λ$在由$L$的系数域和$Γ$定义的新系数域上的分解问题，允许计算$Γ$上的谱层。最终目标是针对一般$λ$，为谱问题$L(y)=λy$发展Picard-Vessiot理论。
英文摘要：
The correspondence between commutative rings of ordinary differential operators and algebraic curves has been extensively and deeply studied since the seminal works of Burchnall-Chaundy in 1923. This paper is an overview of recent developments to make this correspondence computationally effective, by means of differential algebra and symbolic computation. The centralizer of an ordinary differential operator $L$ is a maximal commutative ring, the affine ring of a spectral curve $Γ$. The defining ideal of $Γ$ is described, assuming that a finite set of generators of the centralizer is known. In addition, the factorization problem of $L-λ$ over a new coefficient field, defined by the coefficient field of $L$ and $Γ$, allows the computation of spectral sheaves on $Γ$. The ultimate goal is to develop Picard-Vessiot theory for spectral problems $L(y)=λy$, for a generic $λ$.
