In this talk we discuss the regularity of the Lagrangian Hamiltonian stationary equation which is a fourth order nonlinear PDE. We consider the equation for all phases in dimension two and show that solutions that are $C^{1,1}$ will be smooth. We also derive a $C^{2,α}$ estimate for it.

Note: This talk will be a joint talk of both the geometry/topology seminar and the analysis seminar.

This presentation is oriented at first year graduate cohort within MTH 507, but all interested are welcome. Recent PhD Alumni Timothy Costa (Nvidia), Brandon Edwards (Intel), Thomas Morrill (postdoc at UNSW Canberra) will present their experiences and thoughts on what they do in their job, what helped them to get this job, and what advice they would you to first year grads interested in this type of a job.

In 2011 Robin DiAngelo identified “white fragility” as an emotional/psychological state for white people in which racial stress is intolerable. This racial stress arises when white folks are confronted by their own racial privilege or find themselves in situations that are not racially familiar. This state leads to a number of defensive maneuvers—including outward displays of emotion, argumentation, silence, and withdrawal—in order to restore racial equilibrium. This notion of fragility also makes sense across other forms of social difference—gender, sexuality, and religion.

Congratulations to Choah Shin who will be presenting at SIAM CSE Feb 25-March 1 as one of the participants of the Broader Horizons program (see http://shinstitute.org/the-broader-engagement-be-program/ for details of the program). This is her second time participating in the program; Choah will receive full funding and present a poster "Blow-up Behavior of Conservation Law with Spatially Varying Flux".

Several OSU MATH graduate students and many faculty attended the JMM conference in January. Graduate students representing OSU this year were Sarah Hagen (talk) "A Transition-to-Graduate-School Boot Camp Using Active Learning and Primary Historical Sources," Charles Camacho (talk) "Counting Quasiplatonic Topological Actions of the Cyclic Group on Surfaces," Naveen Somasunderam (talk) "Equidistribution of sequences on the p-adic unit ball, Special Session on Analytic Number Theory," and Allison Arnold-Roksandich (poster) "Establishing Several Infinite Families of Quantum Modular and Mock Modular Forms." Zheting Dong also presented. This information along with other graduate...

Sebastián Naranjo Álvarez will be participating in the Broader Engagement program at the 2019 Computational Science and Engineering (CSE19) meeting of the Society for Industrial and Applied Mathematics (SIAM) in Spokane, February 25-March 1, 2019. SIAM CSE19 conference Broader Engagement (BE) program, organized by the Sustainable Horizons Institute (SHI) will provide a rich scientific program, mentoring, and career and professional development to students to broaden their experience in research-based professional activities. Sebastián has received full funding from the BE program, and he will present a poster on his...

Three mathematics graduate students were selected to attend summer programs next year organized and funded by the MSRI. Daniel Erickson will attend the school on "Recent topics on well-posedness and stability of incompressible fluid and related topics" at MSRI in Berkeley, Choah Shin will attend "Mathematics of Machine Learning" at Microsoft, and Worapon Homsomboon will attend "Geometric Group Theory" in Oaxaca, MX.

Congratulations to Zheting Dong who will present at the Australian-German Workshop on "Differential Geometry in the Large", in Melbourne, Australia, 4-15 February 2019. Zheting received funding from the organizers to attend.
