Research Interests and Projects

/ ·  I am interested in Algebra, including Combinatorics, Representation Theory and Algebraic Geometry.
·  While I got my minor in Computer Engineering, I learned data structures in C and also logical and functional programming. The largest project I worked on was a simulation of a train system using data structures.
·  In my undergraduate thesis I found a basis for the top homology of the non-crossing partition lattice. Though it is not a geometric lattice, I was able to adapt techniques used on geometric lattices to find a basis with elements that are in bijection with binary trees. Then I analyze the action of the dihedral group on this basis.
·  During my first quarter at the University of Chicago I was working on the Abelian sand pile model. I used the software Matlab to design and implement an algorithm to find the equilibrium state on a graph with four vertices, one of them being a sink. The idea of the algorithm is to apply successive combinations of avalanches considering them one single operation. Our algorithm was computationally efficient.
·  In my PhD thesis I studied the algebraic variety of n by n matrices with commutator of rank at most one. I describe its irreducible components; two of them correspond to the pairs of commuting matrices, and n-2 components of smaller dimension corresponding to the pairs of rank one commutator. Even though these matrices don’t commute as endomorphisms of the n-dimensional vector space, they act as commutative operators on a smaller space. By considering this action we define a map to the zero fiber of the Hilbert scheme of points and study the image and the fibers. We used the software Mathematica to produce explicit examples of conjugation classes for matrices of various sizes and for these examples we were able to define the maps that we generalized and used in the proofs. The numerical evidence allowed us to conjecture which maps have homogeneous fibers, and we proved the conjectures algebraically later. We also used Mathematica to disprove the irreducibility of a class of principal nilpotent pairs of nilpotent commuting matrices.
·  As a postdoc at UC Riverside I have been studying a family of partitions defined recursively, and was able to find a non-recursive description with inequalities. Mathematica was used to create the family and check the new description
