Uniqueness in determination of the fractional order in the TFDE using one measurement
Yi Zhang, Xianzheng Jia, Gongsheng Li
This article deals with an inverse problem of identifying the fractional order in the 1D time fractional diffusion equation (TFDE in short) using the measurement at one space-time…

Desingularization in the -Weyl algebra
Christoph Koutschan, Yi Zhang
In this paper, we study the desingularization problem in the first -Weyl algebra. We give an order bound for desingularized operators, and thus derive an algorithm for computing…

Univariate Contraction and Multivariate Desingularization of Ore Ideals
Yi Zhang
Ore operators with polynomial coefficients form a common algebraic abstraction for representing D-finite functions. They form the Ore ring , where is the constant fi…
