SUMMARY:Applied Math Seminar: Victoria Chebotaeva (USC)
DESCRIPTION:Title: Erlang-Distributed SEIR Epidemical Models \nAbstract: \nWe examine the effects of different dynamics in epidemiological models\, focusing on two key approaches. The first model incorporates reaction-diffusion dynamics\, where susceptible individuals avoid areas with high concentrations of infected individuals. The second model divides exposed and infectious individuals into symptomatic and asymptomatic subclasses.\nOur findings emphasize the importance of adaptive control measures\, such as targeted testing\, contact tracing\, and isolation\, in effectively containing disease spread while minimizing societal and economic impacts. The models highlight the distinct roles of symptomatic and asymptomatic individuals\, demonstrating how tailored public health strategies can improve resource management and mitigate the socio-economic effects of outbreaks.

SUMMARY:Jacobians of tropical curves and finite graphs (Carrie Frizzell\, Scripps)
DESCRIPTION:A Jacobian variety is a principally polarized abelian variety (PPAV) associated with a smooth complex algebraic curve. For dimensions less than or equal to 3\, every PPAV is either a Jacobian or a product of Jacobians. The Schottky problem concerns dimensions 4 and greater: which PPAVs are Jacobians? The Schottky problem can also be posed in the tropical setting\, in which the Jacobian of a tropical curve is a real torus. We will spend most of the talk discussing tropical Jacobians and their discrete counterparts\, but we will also survey a few results related to the aforementioned Schottky problem.

SUMMARY:Claremont Topology Seminar: Sierra Knavel (Georgia Tech)
DESCRIPTION:We especially welcome all undergraduates and graduate students to attend topology seminar! \nSpeaker: Sierra Knavel (Georgia Tech) \nTitle: Betti Numbers and Indecomposability of Genus-2 Lefschetz Fibrations \nAbstract: Symplectic 4-manifolds\, smooth 4-manifolds equipped with a closed\, nondegenerate 2-form\, arise naturally in classical mechanics and have become central objects of study in topology. Following foundational work by Donaldson and Gompf\, Lefschetz pencils have been shown to correspond bijectively with symplectic 4-manifolds\, making symplectic 4-manifolds a tractable family of smooth 4-manifolds to work with. This talk focuses on genus-2 Lefschetz fibrations obtained by blowing up Lefschetz pencils and presents new bounds on their first Betti number. We will also examine a particularly elusive class of non-simply connected\, indecomposable genus-2 fibrations and consider the prospects of extending these results to higher genera.

SUMMARY:CCMS Colloquium: (Naneh Apkarian\, Arizona State University\, Arizona)
DESCRIPTION:Speaker:  Naneh Apkarian Professor of Mathematics\, Arizona State University\, Arizona \nTitle: Student Success in an Interactive STEM Ecosystem \nAbstract: This talk begins with a discussion of the multifaceted nature of “student success” in STEM\, including externally recognized markers (e.g.\, grades) and internally defined indicators (e.g.\, enjoyment). Investigations of the factors which contribute to student success along various dimensions\, how to improve student success\, and how to implement successful interventions at scale reveal the complexities of the STEM higher education ecosystem as well as the critical role of introductory mathematics courses. I will review results along these themes\, highlighting interactions which define that ecosystem and support/constrain different aspects of student success\, for different populations. This includes the role of intra- and extra-curricular factors such as student-student interactions\, course coordination\, departmental culture\, and instructors’ beliefs. Implications for research and practice will also be discussed. \nBio: Dr. Naneh Apkarian is an Assistant Professor in the School of Mathematical and Statistical Sciences at Arizona State University. She is from California\, where she obtained a BA and MA in mathematics prior to completing her PhD in mathematics education. Pursuing departmental change as a strategy for transforming mathematics education\, she was for two years a postdoctoral researcher at Western Michigan University. Her research spans many facets of the STEM education ecosystem\, including the knowledge\, beliefs\, practices\, and experiences of students and instructors\, departmental culture\, and interactions within and across levels – always in the service of building inclusive excellence. Outside academia\, Dr. Apkarian continues to play competitive water polo across the US and the world. \n
