Alicia Harper

Doctoral candidate in Mathematics (Brown University)

My name is Alicia, and I am broadly interested in algebraic geometry. I am finishing graduate school under Dan Abramovich at Brown University. My research interests include applications of destackification, semistable reduction of surface singularities, and (twisted) motivic integration.

here was a birthday present i once drew: the great A'Tuin and his world Elephants from the series Discworld.

...and more generically, an unfinished tree:

now for something mathy, here is an illustration of the rational double point singularity of type A and the Whitney umbrella singularity:

even more mathy: the following image illustrate the root stack construction in conjunction with a blow-up. see my paper on Factorization for Stacks and Boundary Complexes for an example of where and how such notions are used.

and finally...have you ever felt at a loss?
