On the zero locus of ideals defining the Nash blowup of toric surfaces
Daniel Duarte, Enrique Chavez Martinez
We consider the problem of finding an ideal whose blowup defines the Nash blowup of a toric surface and such that its zero locus coincides with the singular set of the toric surfac…

Computational aspects of the higher Nash blowup
Daniel Duarte
The higher Nash blowup of an algebraic variety replaces singular points with limits of certain spaces carrying higher-order data associated to the variety at non-singular points. I…
