Applied Mathematics and Computation Seminars

Methane bubbles frozen in the ice of Lake Baikal

The AMC seminar is devoted to general topics in applied mathematics and computation. We welcome an interdisciplinary audience and speakers: faculty, researchers, and graduate students from mathematics, geosciences, computer science, engineering, atmospheric sciences, and other disciplines, to attend and present research talks in their fields as well as reaching across multiple fields. Both technical, tutorial, and expository presentations are welcome.

Attendees are encouraged to join the mailing list by sending an email to the organizer (M. Peszynska).

Students attending regularly are encouraged to sign up for (an appropriate section of) seminar credit under MTH 607. Non-OSU participants from outside academe are also encouraged to write an email to the organizers and provide their names and affiliation.

See below for upcoming seminars or access the seminar archive.

Stefanie Fazekas and Eduardo Ramos-Arteaga joint talkTITLE: Discussion of Sabac's result on sharpness of O(\sqrt{h}) convergence rate ABSTRACT: It is well known that monotone finite difference schemes for linear conservation laws with smooth initial data converge with order O(h). However, for non-smooth initial data and nonlinear flux, we only obtain convergence of order O(\sqrt{h}). In [Sabac, 1997] this rate is proved to be sharp. We give an outline of how this result is derived by constructing appropriate initial data.Stefanie Fazekas talkTITLE: An exploration of nonlinear coupled PDE models for flow and heat transport ABSTRACT: We consider a nonlinear coupled PDE model given by a (1) Darcy flow model coupled to a (2) heat transport model. First we discuss relevant results from literature on similar models. Next we outline our approach which is unique in that analytical and semi-analytical solutions can be found. Convergence analysis for a FV scheme is of order square root under… Read more.
