## Recent projects

Here is a list of recent undegraduate research projects. When available, we have added images that give you a flavor of some of the topics studied. If the student wrote a thesis, you can look it up at USM's library.

- "Surfaces of Revolution with Constant Mean Curvature
*H=c*in Hyperbolic 3-Space**H**^{3}(-*c*^{2})", Kinseyann Zarske, Undergraduate Student Paper Competition, 2013 meeting of the LA/MS Section of the MAA.

- "Triangularizing matrices without swapping columns", Lorrin Debenport, Honors Thesis, 2011.
Examples of the near-triangularity of the **Macaulay matrix**. - "Special Matrices, the Centrosymmetric Matrices", Benjamin Benson, Undergraduate Thesis, 2010.
- "Tropical Mathematics", Matthew Dixon, Undergraduate Project, 2010.
One line contributes nothing to the **tropical polynomial**on the left. The tropical polynomial on the right is**fully reduced**, because all the lines contribute.A **dense**tropical polynomial: if the slope of line*i*is*m*, then_{i}*m*_{i}_{+1}=*m*+1._{i} - "A criterion for identifying stressors in non-linear equations using Gröbner bases", Elisabeth Palchak, Honors Thesis, 2010.
Trying to compute a vector common to *L*_{1}and*L*_{2}gives rise to an interesting multivariate, polynomial system. - "Method of approximate fundamental solutions for ill-posed elliptic boundary value problems", Christopher R. Mills, Honors Thesis, 2009.
- "Problems in the College Math Journal", Ashley Sanders, Undergraduate Project, 2009.
- "Dodgson's method of computing determinants", Deanna Leggett, Undergraduate Project, 2008.
**Dodgson's Method**fails if an interior matrix has determinant zero.The **double-crossing method**fixes this by choosing a different matrix for the division. More details in the full paper.
