Undergraduate Research Opportunities
Current undergraduate research opportunities in the Mathematics Department are described below. For further information, contact the listed faculty member.
Undergraduate projects could involve studying various aspects of evolution, ecology, or disease transmission in populations where interactions are restricted by spatial location or some form of contact network (perhaps governed by behavior, social status, etc.).
Some familiarity with rates of change (calculus or differential equations) and experience with a coding language would be helpful. Some knowledge of biology is also useful. Interest and the willingness to work hard are the most important prerequisites.
This project is in discrete mathematics, particularly in graph theory. The topic is about the existence of substructures of a graph. Given a graph G = (V, E) of order n and a subset W of V , let every vertex of W have degree at least 2n/3. Conditions on vertices of V - W are unknown. What will be the impact of W on the structure of G? For example, are there disjoint cycles of G passing through prescribed numbers of vertices of W? When W = V ,this topic has been investigated extensively. When W is a proper subset of V, i.e., W is a subset of (or is included in) V and W is not equal to V , this topic is introduced in the following publication:
H. Wang, Partial Degree Conditions and Cycle Coverings, Journal of Graph Theory, 78(2015), 295-304.
Substructures other than cycles can be considered as research projects, too. Some weak conditions can be imposed on the vertices which are not in W for the research purpose.
Students should have strong interests in discrete mathematics. It is desirable that students have some knowledge of discrete mathematics, for instance, having taken Math 176 (Discrete Mathematics) or other combinatorial courses. It is also desirable that students have taken Calculus I, Calculus II, and Linear Algebra.
Frame theory in the finite dimensional setting is a branch of applied linear algebra. Frames are like bases but go beyond: they are used to represent spaces but they allow a lot more flexibility than bases. Frames have become a standard tool in signal processing and are behind the technology of digital cameras, cell phones, and other communication devices. They are used by the FBI to efficiently store fingerprints of millions of individuals. Some of the important problems in this area look at constructing frames with nice properties that make signal reconstruction efficient and signal transmission robust to transmission losses.
Linear algebra (330). It would also be helpful to have taken 430, 461, or, 471.
