Title: On Volterra Quadratic Stochastic Operators of a Two-Sex Population

Abstract: We consider a family of operators which model the behavior of a current generation and its trajectory for future generations. We observe the fixed points of our operators and the way trajectories behave around these fixed points. We use the eigenvalues of the Jacobian matrix of our operator to find the type of fixed points of the operator.

Title: An Analysis of Obesity and Climate Change in the United States

Abstract: Obesity and climate change have become a major issue in the United States. To gain a better understanding on how obesity impacts the environment, we analyzed Edwards and Roberts' study (2009), "Population adiposity and climate change." They made very strict assumptions regarding the United Kingdom in the 1970s and in 2010. To better represent the United States, we made our own assumptions so we could grasp an understanding on how changes in BMI are affecting greenhouse gas emissions. Specifically, the study focuses on greenhouse gases emitted from food production, vehicle transportation, and air travel. We found that their assumptions were relatively consistent with our normal weight population. However, Edwards and Roberts' predicted 2010 population had greatly underrepresented estimates compared to our hypothetical overweight population, thus suggesting that a raise in BMI is indeed causing greater emissions to be emitted due to food production, vehicle emissions, and aviation fuel demands.

Title: Virtual Trivalent Braids

Abstract: This talk is based on my summer research experience during the 2017 Mathematics REU (Research Experience for Undergraduates) at Fresno State. Come learn some cool stuff about braids and their geometric and algebraic properties.
