Daphne Klotsa, University of North Carolina at Chapel Hill, A touch of non-linearity at intermediate Reynolds numbers: where spheres “think” collectively and swim together
SAS 4201From crawling cells to orca whales, swimming in nature occurs at different scales. The study of swimming across length scales can shed light onto the biological functions of natural swimmers or inspire the design of artificial swimmers with applications ranging from targeted drug delivery to deep-water explorations. In this talk, I will present experiments and simulations…
Alie Falastien, Conor Perks and Jaye Sudweeks, Honors Students Research Presentation
Alie Falastein Title: Connectivity Estimation in Neuronal Networks: The Hidden Node Problem Abstract: The human brain is a complex system consisting of billions of neurons. The network connectivity of these neurons gives rise to a variety of dynamical behaviors and understanding it is key to describing the underlying evolution of the system. However, in our analysis of…
The Fourth Duke Mathematical Journal Conference April 26-29, 2018
Duke UniversityThe goal of this conference is to bring young mathematicians together, both as speakers and as participants. The talks will cover an array of subject areas that are well represented in the Duke Journal. There will be nine talks by young mathematicians. More information can be found at: https://sites.duke.edu/dmj2018/
Faye Pasley, Molly Lynch, NC State
Speaker 1: Faye Pasley Title: Determinantal Representations, the Numerical Range, and Invariance We study hyperbolic polynomials with symmetry and express them as the determinant of a Hermitian matrix with special structure. By properly modifying a construction of Dixon (1902), we show for every hyperbolic polynomial of degree $n$ invariant under the cyclic group of order $n$ there…
Maggie Figueroa, Olivia Trogdon, Benjamin Wendt and Gautam Niagara, NC State, Honors Students Research Presentation
Maggie Figueroa Title: Breaking Cryptography – the Discrete Log Problem Abstract: The goal of cryptography is to allow ciphertext to be decoded only by the intended recipient. The privacy of the message relies heavily on the key used in the encryption function. Once a key is obtained, the decryption function follows easily. Cryptosystems such as…
Rosalie Bélanger-Rioux, Harvard University, Strategies for Supporting Diversity in Mathematics Departments
SAS 1102There are many reasons, moral and practical, why we need to diversify our mathematics departments — and more generally STEM departments and the workforce. But how do we go about it? A good starting point is to realize the various barriers to an inclusive environment. In this talk, a case study will be used to…
Emily Barnard, Northeastern University, Graph Associahedra and the Poset of Maximal Tubings
SAS 4201Given a graph G on n vertices, Postnikov defined a graph associahedron P_G as an example of a generalized permutohedron, a polytope whose normal fan coarsens the braid arrangement. Combinatorially, each face of P_G corresponds to certain collections of compatible subgraphs of G called tubings. Graph associahedra were introduced independently by Carr and Devadoss and…
Diversity and Inclusion Brown Bag Lunch
SAS 3282For a reading this time, I suggest this interview with Rochelle Gutiérrez, which was just published in the Notices of the AMS this month, and which I have attached. Juanita had suggested Professor Gutiérrez as a possible colloquium speaker, and I think that the interview makes an interesting read. Also, I will mention the Statistics…
Fall 2018 Mathematics Department Reception
SAS 4104Starting at 3:30 PM, please join us in the Commons, SAS 4104, before tomorrow's Fall Department Meeting for NC State's own Howling Cow ice cream!
Fall 2018 Math Departmental Meeting
SAS 1102Tye Lidman, NC State, Spineless 4-manifolds
We construct smooth compact 4-manifolds homotopy equivalent to S^2 which do not contain nicely embedded spheres realizing the homotopy equivalence.
Fall 2018 Math Faculty Meeting
SAS 4201This meeting is for the COS administration to meet and speak with the math faculty. Dean McGahan will start the discussion and will have a Q&A session at this meeting. Also, Debbie Carraway, COS Director of Information Technology, Meghan Kerr, COS Director of Research Administration, and Roy Baroff, NC State Faculty and Staff Ombudsman, will…
Weekly Brown Bag Lunch
SAS 4104Join AWM as they host their weekly brown bag lunch in SAS 4104.
AWM Welcome Event
AWM is hosting a welcome event on Friday, Aug. 31st from 3 - 4:30 pm. Please join us for an ice-breaker activity and snacks as we (hopefully) meet some new members. Let new office or classmates know how fun we are and encourage them to come! Remember, AWM is not just for women rather we…
Curtis Porter, NC State, Spinning Black Holes and CR 3-Folds
Some physically significant solutions to Einstein's field equations are spacetimes which are foliated by a family of curves called a shear-free null geodesic congruence (SFNGC). Examples include models of gravitational waves that were recently detected, and rotating black holes. The properties of a SFNGC induce a CR structure on the 3-dimensional leaf space of the…
