Joint Dynamics and PDE Seminar

The Boston University Department of Mathematics and Statistics and Brown University's Department of Mathematics and Division of Applied Mathematics hold joint seminars on topics in dynamics and PDE. The schedule and locations for these events can be found below. For a list of all past events of the seminar please visit the BU/Brown PDE Seminar Archive.

The organizers for the Brown/BU Seminars are Jason Bramburger and Ryan Goh.  Please contact them at jason_bramburger@Brown.edu or rgoh@bu.edu.

Spring 2018

Thursday, April 19 2:00pm - 6:00pm at Brown

Recent experiments show that bacterial and other active suspensions in confined geometries can self-organize into persistent flow structures that exhibit spontaneously broken mirror symmetry.

Jingwei Ma

Recent advances in X-ray tomography and high performance computing enable modeling of the spatio-temporal dynamics of signaling pathways within a realistic 3D mammalian cell. We study the process of a chemical signal that is activated at random locations on cell membrane diffuses across cytosol and into nucleus.

Efstathios G. Charalampidis

In this talk, we will discuss the dynamics of rogue waves in nonlinear Schrodinger (NLS) equations and discrete variants thereof. Initially, we will consider NLS equations with variable coefficients which can be converted into their integrable siblings by utilizing suitable transformations. Then, the Peregrine soliton will be fed to the transformation employed.

Allen Wu

The equilibrium shape and density distribution of rotating fluids under self-gravitation is a classical problem in mathematical physics. Early efforts before the twentieth century revealed ellipsoidal solutions with constant density.

Ang Li

Planar spiral waves have been observed in many natural systems and also as solutions of reaction-diffusion equation.

Pedro J Saenz

We demonstrate the spontaneous emergence of collective behavior in spin lattices of droplets walking on a vibrating fluid surface. Circular wells at the bottom of the fluid bath encourage individual droplets to walk in clockwise or counter-clockwise direction along circular trajectories centered at the lattice sites.

Yernat Assylbekov

The attenuated geodesic ray transform is the integration of functions over geodesics with the exponential weight factor. This is the theoretical backbone of medical imaging techniques such as SPECT and Ultrasound Tomography. In applications, we often encounter such transforms acting on tensor fields.
