Papers

I have published papers in five areas: Numerical Solution of Singularly Perturbed Differential Equations, Knowledge Compilation, PDE based Image Restoration, Regularization in Learning Theory, and Numerical Linear Algebra. These are in the subsection Reseach Papers. I also have papers in basic mathematics such as school geometry and basic set theory. See the following subsections.
