Andrea Giorgini - Department of Mathematics, Indiana University
Sep 13, 2019 - 10:00am to 11:00am
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 025
Diffuse Interface models are nowadays widely employed in Fluid Dynamics to model the free interface motion of mixtures of two different fluids or phases. In this approach, the interface is represented as the zero level set of a label function (or difference of fluid concentrations), whose values \(... read more

Qing Cheng - Department of Applied Mathematics, Illinois Institute of Technology
Sep 11, 2019 - 5:00pm to 6:00pm
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 025
We develop a Lagrangian numerical method (the flow dynamic approach (FDA)), based on the Energetic Variational Approach (EnVarA), motivated by Rayleigh and Onsager. The method posses advantages in capturing the sharp interface, comparing with numerical methods in Eulerian coordinates. As... read more

Oleksii Mostovyi - Department of Mathematics, University of Connecticut
Sep 10, 2019 - 11:25am to 12:30pm
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 119
We consider a problem of optimal consumption from investment and labor income in an incomplete semimartingale market. We introduce a set of constraint times, i.e., a set of stopping times, at which the wealth process must stay positive, in a unifying way such that borrowing against the future... read more
