Maria Agnesi Activity, Cynthia J. Huffman Ph.D.
Open Educational Resources - Math
This activity was originally created for a Women in Mathematics course to provide students with a small taste of some basic mathematics connected to the work of Maria Agnesi. The activity has the students look at some of her work in algebra and calculus (optional). It could also be used in other courses, such as history of math, a general education mathematics course, high school or college algebra, and calculus.

Theses and Dissertations
Solutions to the one-dimensional and two-dimensional nonlinear Schrodinger (NLS) equation are obtained numerically using methods based on radial basis functions (RBFs). Periodic boundary conditions are enforced with a non-periodic initial condition over varying domain sizes. The spatial structure of the solutions is represented using RBFs while several explicit and implicit iterative methods for solving ordinary differential equations (ODEs) are used in temporal discretization for the approximate solutions to the NLS equation. Splitting schemes, integration factors and hyperviscosity are used to stabilize the time-stepping schemes and are compared with one another in terms of computational efficiency and accuracy.
