Mathematical Relativity And The Nature Of The Universe, Priscila Reyes
Mathematical Relativity And The Nature Of The Universe, Priscila Reyes
Mathematics Colloquium Series
In this talk, I will be discussing certain space-times, which can be used to model celestial objects and events in the universe. These are solutions to Einstein's field equations, which roughly describe the relation between matter, energy and the geometry of the universe. The concept of time in relation to an observer will be demonstrated. I will also include some interesting phenomena that arise out of the unusual mathematical structure of space-times , such as Lorentz contraction, reverse Cauchy-Schwarz, and the twin paradox.
Mathematical Optimization And Applications, Teodora Suciu
Mathematical Optimization And Applications, Teodora Suciu
Mathematics Colloquium Series
This talk centers on mathematical optimization in the context of Calculus of Variations. Optimization involves choosing the best element from a set of choices, usually through mathematical approaches. Solving these kinds of problems is considered an essential tool in many areas of science and engineering. Additionally, various mathematics and business applications are discussed. Also explored is a real-life example with a detailed algorithm that is closely related to the Traveling Salesman problem.
Minimum Number Of Distinct Eigenvalues Of Graphs, Shahla Nasserasr
Minimum Number Of Distinct Eigenvalues Of Graphs, Shahla Nasserasr
Mathematics Colloquium Series
For a simple graph G on n vertices, a real symmetric nxn matrix A is said to be compatible with G, if for different i and j, the (i; j) entry of A is nonzero whenever there is an edge between the vertices i and j, it is zero otherwise. The minimum number of distinct eigenvalues, when minimum is taken over all compatible matrices with G, is denoted by q(G). In this talk, a survey of some known and new results about q(G) is presented.
Continuous Dependence And Differentiating Solutions Of A Second Order Boundary Value Problem With Average Value Condition, Samantha A. Major
Continuous Dependence And Differentiating Solutions Of A Second Order Boundary Value Problem With Average Value Condition, Samantha A. Major
Mathematics Colloquium Series
Using a few conditions, continuous dependence, and a result regarding smoothness of initial conditions, we show that derivatives, with respect to each of the boundary data, of solutions to a second order boundary value problem with an average value integral condition solve the associated variational equation with interesting boundary conditions.
What Can You Do With A Math Degree Anyway?, Steven Thorsen
What Can You Do With A Math Degree Anyway?, Steven Thorsen
Mathematics Colloquium
This talk presents what can be done with a degree in mathematics in these exciting times. Often, those finishing a four-year degree have little idea what to expect in a career outside of teaching. This presentation will outline the possibilities and the speaker will discuss from experience potential careers, the market place, how to start, and some surprising examples of what mathematicians do. Tips for job seekers are included and a lively Q&A will follow.
Spatial Population Models With Fitness Based Dispersal, Chris Cosner
Spatial Population Models With Fitness Based Dispersal, Chris Cosner
Mathematics Colloquium Series
Traditional continuous time models in spatial ecology typically describe movement in terms of linear diffusion and advection, which combine with nonlinear population dynamics to produce semi-linear parabolic equations and systems. In environments that are favorable everywhere in the sense that the local population growth rate is always positive, organisms can use linear advection and diffusion to achieve an optimal spatial distribution. (Here optimal means evolutionarily stable.) In regions where there are environmental “sinks” where the local growth rate is negative, it does not seem possible to achieve an optimal distribution via linear dispersal. It is possible for organisms using advection …

Modeling And Methods Of Signal Separations With Applications In Spectroscopic Sensing, Yuanchang Sun
Modeling And Methods Of Signal Separations With Applications In Spectroscopic Sensing, Yuanchang Sun
Mathematics Colloquium Series
Spectroscopic sensing is a powerful and a widely used family of techniques for detecting and identifying chemical and biological substances. For example, nuclear magnetic resonance (NMR) relies on the magnetic properties of the atomistic nucleus to determine the molecular structures. Raman spectroscopy (RS) uses laser light scattering and the resulting energy shift of photons to sense the vibrational modes of a sample. In remote sensing, hyperspectral imaging (HSI) makes use of hundreds of contiguous spectral bands to identify nearly invisible objects at subpixel level. Differential optical absorption spectroscopy (DOAS) is based on the light absorption property of matter to identify …

Exploring Argumentation, Objectivity, And Bias: The Case Of Mathematical Infinity, Ami Mamolo
Exploring Argumentation, Objectivity, And Bias: The Case Of Mathematical Infinity, Ami Mamolo
OSSA Conference Archive
This paper presents an overview of several years of my research into individuals’ reasoning, argumentation, and bias when addressing problems, scenarios, and symbols related to mathematical infinity. There is a long history of debate around what constitutes “objective truth” in the realm of mathematical infinity, dating back to ancient Greece (e.g., Dubinsky et al., 2005). Modes of argumentation, hindrances, and intuitions have been largely consistent over the years and across levels of expertise (e.g., Brown et al., 2010; Fischbein et al., 1979, Tsamir, 1999). This presentation examines the interrelated complexities of notions of objectivity, bias, and argumentation as manifested in …
